  3. 3. Collier-Zans, Erin, *6520 101/2011 Five-Year Plan, 2011 In one year’s time, I foresee myself at a new college or university. I will be well onmy way to completing all core/liberal-arts mandated course work and degree prerequisites. Iwill be in regular contact with my advisor, and will have elicited their assistance in planningout my schedules for the following semesters (with enough detail that I can create aflowchart, so that there can be no confusion when class registration rolls around). I will alsobe in contact with department heads/chairs and/or instructors from the majors in which I’minterested in pursuing, so that I can be sure that I’m prepared for all coursework, andunderstand before going in what exactly the focus’ of these programs are. By the end of theyear, my major will have been declared and I will have begun junior/senior level worktherein. I will have settled into a calm living situation, conducive for learning and my ownmental and physical health. If I’m in a dorm, I will understand all rules and policies, and beable to plan ahead for the coming year(s). If in an apartment, I hope to have found some placesmall, quiet and in a good neighborhood, with good access to bus and/or pedestrian routes. Iwill either have a work-study (hopefully) or have found a part-time job in something I’minterested in (book/art store, etc) and be able to pay for my own living expenses, andhopefully some of my monthly tuition payments. In two year’s time, I will have declared my major and be well into prescribed coursework. I will have already finished the planning and begun some of the preliminary work formy senior thesis/capstone project – I will have likely sources, and have pinned downfieldwork contacts and opportunities, hopefully with the assistance of instructors who’vedone work in the field. Ideally, I will already have begun my fieldwork, and be keeping upwith the academic work associated with it. I will also have done a semester abroad, aninternship, or something of the kind, both for fun and hopefully relating to said final product.I will already have done research on post-graduation options, and have some idea by middleof my second year what my next steps will be. I hope to have a strong feeling, either ofengagement in a particular area (in which case application to a graduate program will be wellin the works) or of ambivalence (in which case I will already have applied to an internship orto the Peace Corps – something non-academic that will get me working and help me clear myhead).
  4. 4. Collier-Zans, Erin, *6520 2 In three year’s time, if I haven’t already graduated with a single major, I will begraduating with a major/minor or a double major. Much of the above applies, if I’ve justfinished my bachelor’s at the three-year mark, but if I’ve already been out for a year, then Ihope to have a good idea of what field I would like to start my first career in. I will eitherhave finished an internship and be working/attending graduate school, be in the middle or inbetween internships, be in the middle of my first masters degree, or in the middle of a PeaceCorps tour. Any of the above should be able to help me refine my focus, if it still needsrefining at the age of twenty-three, and by the end of the third year I should have tentativeplans for my next steps in mind. At four years, I will either be working, or be pursuing an even higher level ofeducation – either finishing a Graduate degree, or attending medical school. I will be on myway to financial security, with some idea of what my average income will be, and should beable to handle tuition/loan payments, etc. I have begun taking leases on my residences, and beable to plan my movements and plans at least six months in advance. I will be able to handleany familial eventuality. In five years time, I will either have finished my graduate degree and be employed inthe field, hopefully doing research and working on my first scholarly publications, or I willbe finishing medical school and beginning my internship as a general surgeon. I will have afirm idea at this point of what my basic moral coda is (and hopefully be able to articulate it),and understand fully why I am doing whatever it is I am doing; I want there to be no doubt inmy mind that the work I am doing is good and important, and valuable to the (global)community. I will be handling loan payments and living expenses well and be living simply, witha healthy short-term savings account and be making (even small) monthly deposits to aretirement fund. By twenty-five I will have made exercise a much bigger priority in my life,be able to run a 10K at least once a month, and be on my way to training for a full marathon.At this point I should start making health decisions that will effect the rest of my life –corrective surgery on my feet and allergy shots may be considered at this time (if theyhaven’t been already). I will be able to play guitar, will be proficient in more media and bedoing art at least once weekly, and will have begun to pursue other interests and hobbies, i.e.learning a new language or instrument, etc. I will have completed the manuscript of at leastone book (hopefully a trilogy) and be well into the editing process. I will be able to ride abike by this point, as well. Finally, at twenty-five I will be able to draft a tentative five-yearplan to carry me through to thirty, with opportunity to reassess at that point.
  5. 5. Collier-Zans, Erin, *6520 31. Financial: a. In school: i. Find job (preferably work-study), plan out time to balance school/work ii. Create an honest monthly budget – review transactions at the end of the month, have self-planning sessions to set reasonable goals for the next month iii. Split all extra earnings and deposit in short-term/retirement accounts – plan to save at least of total earnings 10% monthly. iv. Speak to financial advisor (use parent’s?), do research and understand basics of the financial system. v. Make periodic purchases of stocks/bonds etc when funds allow, begin creating a portfolio, get help on this. vi. Get parents’ help learning how to fill out/file taxes – become fluent with the various tools available. vii. Assess living situation; are dorms more practical, with cooking limitations, noise, etc than an apartment/lease, which may be more expensive but save money in terms of grades, time, etc? Consider this according to budget, time constraints, personal preference, housing availability – all possible factors. viii. Assess loans – will I be able to pay them off after school? Take only what I am sure of being able to handle. b. Three years (out of school) i. Re-asses portfolio, savings accounts, assets, investments. Do whatever periodic maintenance is necessary on this. ii. Assess next steps – am I financially secure enough at this point to drop everything and do a Peace Corps/similar tour? iii. Re-asses loans – create new monthly budgets, set up automatic payments near the beginning of the month, keep to the budget and reassess monthly. iv. Write-out monthly/bi-monthly goals, plan ahead for recreational spending, don’t touch savings accounts – set up third savings for short- term spending money, re-allocate other moneys to emergency savings, continue making deposits in retirement fund. c. Five years (beginning career) i. Assess goals. Make sure that next steps will not set me back financially, but hopefully continue to carry me forward, or that I can at least maintain at healthy level. Options: 1. Graduate school. 2. Begin career, put off masters/doctorate a few years (this would be for loan purposes, if earnings will not be high enough during/after graduate school to handle additional loans/cost of living during school time – health of savings account and other assets may be a factor) 3. Medical school (same concerns as for graduate school)2. Career: a. Three years: i. Best option: take time to continue education, either graduate or medical school. ii. Other options: assess whether I have any strong feelings on the matter. If not, take time to travel, join Peace Corps, live in another country,
  6. 6. Collier-Zans, Erin, *6520 4 work in wilderness – find some way to jump-start myself, take space, create the sense if not the reality of freedom so that I don’t get bogged down in no-where jobs, feeling like I’m stuck. iii. If yes, take action. See options, above. b. Five years: i. Best option: if it hasn’t happened already, make additional schooling a reality – graduate/medical. ii. If time was taken off, assess if I now have any strong feelings. If yes, take steps, if no, seriously consider my sanity.3. Physical: a. One year: i. Learn to ride a bike. ASAP. ii. Assess health/life insurance ASAP: what do I do w/o Cover Colorado? School-provided insurance? Assess options, fit various into budget, then take a plan. iii. Be able to run three miles comfortably. Continually assess foot situation – do they still feel healthy, safe? If not, speak with parents about surgical options. iv. Keep track of body/fat%/calories – make sure that I am maintaining myself, keeping myself healthy. v. Begin doing 5Ks on weekends. Look for sponsors? vi. Stop biting my nails. Do whatever it takes. Find alternate means to relieve stress. vii. Continue to work on posture – improve on what I already have, work on holding head up and back, consciously work on making attitude of assertive confidence a constant. b. Next three years: i. Be doing five miles in three years, three times a week. Continue to monitor status of my feet. ii. Consider getting shots for cat allergies.4. Relationships: a. Next five years: i. Work through anger with my father – neutrality is better than resentment. If necessary, decide not to care and stick to it. ii. Continue being supportive of my mother – don’t let my feelings get in the way, honestly assess what will be healthiest for her, keep control of my tongue so that I am not being hurtful. iii. Spend time with grandmother. iv. Look people firmly in the eyes while talking to them, work on projecting confidence, even if I’m not feeling it. v. Work on keeping calm, self-contained when interacting with others. Work on being self-aware, even in engrossing situations – this will give me the ability to be more aware of what others are doing, which will enable me to respond appropriately, in a way that will be more appreciative of and kind to others.5. Spiritual: a. Next five years: i. Reassess my spirituality. Purge as much indoctrination as possible, find out what I really believe using my thoughts, actions, and reactions as reference points.
  7. 7. Collier-Zans, Erin, *6520 5 ii. Re-discover the loving, spiritual connection I have with non-human world and reality. iii. Re-learn to cultivate silence – God is in the silence.6.

Make plans for masters/doctorate/medical school – now, or later? iv. Learn to read music. v. Be relatively fluent on guitar. Be proficient enough to start learning classical Spanish pieces. vi. Start working on violin – get great-granddaddy’s repaired, if need be, or buy a used student’s model, get a book, and start learning. vii. Know how to quickly, cheaply and efficiently retrofit an apartment to be more environmentally conservative/secure – caulking, heater fixes, window wrapping, etc. b. Next five years: i. Start working with kids again – work at a daycare, volunteer, something. They have so much to teach! ii. Keep an eye out for a cheap-ish copy of Rosetta Stone, start working through languages. Priorities: Spanish (Spain), French, Irish, Swedish, Arabic, Hindi, Portuguese. iii. Get a Wacom tablet, work on my digital art skills iv. Practice with acrylic/oil paints, improve my still-life/portrait skills. v. Get into a figure drawing class, work on figure studies – keep a journal, in order to track progress. vi. Keep subscriptions to a couple of journals pertinent to my majors, keep up to date wit the new research. vii. Keep reading – go through bibliographies and keep up a rolling book list (but find ways to avoid buying new books) 1. Keep notes – write a short essay after each chapter/book, in order to better absorb what I’m reading.7. Fun: a. Next five years: i. Research for and write books: the two publishable books I have plans for, also keep notes on ideas for more & get started outlining. Shoot for having at least one in one series done in five years – preferably a whole trilogy. ii. Write short stories as they come to me – try to get them published, and if they don’t catch, then put them on a blog or something. iii. Work on art – take ref photos, draw from them, write down/quick- sketch ideas, get to the point where drawing digitally is fun, rather than tedious – start posting on dA, consider taking small commissions on the side, as time allows. iv. Plan graduation trip, for my mom? Something that would be fun for her – start saving for this ASAP. v. Take a sailing trip, or something. Something to be on/near the sea. Semester at sea, during school, maybe? Anyway, learn how to sail.

Go to a film festival somewhere.viii. Go to a Broadway show – maybe Ave Q, S Pacific, something like that. ix. Continue going to Cirque shows – take mom! x. Keep up with things my mum wants – what sorts of things is she interested in doing/seeing? Maybe plan another Santa Barbara trip for two-five years from now.
  9. 9. Introduction to College Course Work 2008-2010 What follows is a small selection of my academic work from the past two years,including teacher comments when available. I believe that these three pieces exemplify my workat Naropa, and though I have some issues with their quality and content looking back, I believethat they are at least a fair demonstration of my capabilities at this point. The first is the final paper I wrote for ENV100: ‘Physical Geography – Beholding theBody of the Earth’ – the only geography class required for the Environmental Studies major atNaropa. My topic of research, as you may have guessed, was the phenomenon of glacial isostasy.In writing this piece I learned to navigate the online world of scholarly journal publications, andthe experience of reading researched, scientific articles was like a breath of fresh air. I trulyenjoyed writing the resulting paper. The second is the final piece for ENV207: ‘History of the Environmental Movement’, forwhich I did a cursory study of the history of the German Green Party, or Die Grünen, from the1960s through 80s. In addition, I have left my response to the final question assigned by theinstructor attached to the end of the document; it contains my most recent thoughts on theenvironmental movement and my place, or possible lack thereof, in it. ‘On Hannah Arendt’ is a short paper I wrote in response to said author’s On Violence, anilluminating work on the nature of power, violence, and the present world order. This piece waswritten in 2008; my opinions have changed somewhat and I have developed as a writer, but it isa good example of the sort of texts I grappled with in my Peace Studies classes.
  10. 10. Zans 1Erin Collier-ZansAnne ParkerENV100 Physical Geography2/12/10 Glacial isostasy is directly related to the planet’s climate and hydrological cycle, andpossibly even to the movement of tectonic plates and the planetary gravity field. Because wein the present day are living in an interglacial warming period we are clearly able to detectnatural isostatic effects, but it is now clear that anthropogenic global warming hasexacerbated the natural rate of glacial melt creating these effects. Similarly exacerbatedisostatic response is to be expected, and may already be occurring. This may instigate agreater occurrence of tectonic plate-related natural disasters, such as earthquakes, tsunamis,and volcanic events. The purpose of this paper is to investigate and summarize currant understanding ofthe phenomenon of glacial isostasy, and then give a brief overview of what research has beendone on the isostatic-related effects of glacial melt and sea-level rise in the present, warmingclimate. “Isostasy,” in the broadest sense, is the “general equilibrium in the earth’s crustmaintained by a yielding flow of rock material beneath the surface under gravitative stress”(Mirriam-Webster). An important term to understand here is ‘lithosphere,’ which is “thesurface shell of the earth, [capable of] sustaining long-enduring stress differences withoutsignificant flow,” or the “[that] which comprises the crust, which is relatively cold and brittle,and the uppermost part of the mantle that is relatively cool, strong, and elastic” (Wolf 96;Gornitz 374). When pressure is applied to an elastic surface floating on top of a viscous orliquid substratum, the part of the surface absorbing this imposed pressure will sink or be
  11. 11. Zans 2depressed into the liquid below. When seen on a planetary scale, this phenomenon is anexample of ‘isostasy.’ The term isostasy was first coined by Dutton in 1889 to “describe the apparently‘compensated’ state of Earths surface topography… [though] the idea that such compensationmust occur dates from the studies performed by both Airy (1855) and Pratt (1855) basedupon the observations of plumb line deflections made during the original geodetic survey ofIndia” (Peltier 111). A more detailed description is given by Nansen (c.1928): “The earth’s crust may… be considered as a slowly flexible sheet of solid rock floating on a viscous substratum. If loaded in one place this sheet will bend slowly under the load, and the plastic matter underneath will be displaced to the sides… if unloaded in one place the sheet will rise slowly in that area; there will be an inward flow in the substratum underneath, and a slight subsidence of the sheet in the surrounding area” (qtd in Wolf 99).The concept of isostasy was originally developed in relation to mountains (which are anexternal load simultaneously integrated into the crust) (Peltier 111; Gornitz 374), but itapplies equally well to the compensation of the Earth’s surface to superimposed mass, liketransient glaciers or the more permanent ice sheets present at the poles. The above phenomenon is called “glacial isostasy.” The first use of this term wasmade during the second half of the nineteenth century (Wolf 95), and in the broadest sense itrefers to “the response of the solid Earth to any changes in the planet’s ice sheets” (Gornitz,374). More specifically, it is “the process of lithospheric depression beneath the weight of anice sheet and subsequent rebound when the ice mass is reduced or removed” (“GlacialIsostasy and Eustasy,” Aber). A more detailed description of the process of glacial isostasy isgiven by Aber:
  12. 12. Zans 3 “Lithospheric depress of [hundreds] of [meters] takes place beneath large ice sheets due to the static weight of the ice mass. This excess loading causes elastic and plastic deformation in the lithosphere and underlying asthenosphere. Crustal rock is displaced as the mantle sinks. Given ice density of 0.9 g/cm3 and mantle rock density of about 3.3 g/cm3, the potential depression beneath an ice sheet 1000 m thick could be as much as 275 m.” When mass, like a great volume of ice, is added to the planet’s surface, the initialresponse will be an “elastic deformation of the entire lithosphere-mantle followed by aviscous creep as the mantle stresses relax and the load is increasingly supported by thelithosphere. The local isostatic limit will be attained as a limit” (Gornitz 375). Conversely,“when the ice sheet is removed, the initial response is elastic followed by a viscous rebound”(375). This would seem to imply that, hypothetically, if a glacier were to suddenly bedropped onto a section of continental crust, a broad area of the surface would be depressed toa lesser initial degree, with the localized severity of the depression increasing as the totalextent of the depression gradually decreased over time, until the isostatic limit was achieved,which according to Aber rarely if ever occurs since “several [thousands of] years are requiredfor complete isostatic adjustment to take place, by which time ice thickness has oftenchanged” (“Glacial Isostasy and Eustasy”). Related to the above is the phenomenon of “bulging” in relation to isostatic depress,where, “in order to compensate for lithospheric depression beneath a crustal load, thesurrounding area may [rise,] creating a forebulge. These principles are demonstrated by theAmazon delta, where huge sediment loading has created a central depression that issurrounded by peripheral uplifts… in like manner… the glacial forebulge subsides when theice mass is reduced or removed” (Aber).
  13. 13. Zans 4 The two above phenomena paint a clear picture: as a glacier forms it gradually settlesfarther and farther into the lithosphere, and a bulge is formed around it to compensate for thematter it displaces beneath. When the ice is removed through melting, the land beneath theice rebounds swiftly (i.e. elastically) to a certain comfortable point, and then it graduallycreeps up to its natural position of equilibrium (that is, unless more ice forms over it before itcan accomplish this). As the edges of an ice sheet melt, then, the land rebounds and the bulgemoves inward, and presumably as the ice’s total mass decreases the lithosphere beneath theremaining sheet rebounds slowly in a more viscous fashion as the weight forcing itdownwards diminished. In beds created by stationary, intraplate bodies of ice during glacial periods in theplanet’s Quaternary cycle, thee bulges would gradually erode into the two bordering troughs(the glacial valley and the land directly outside of the bulge), possibly causing the crust toonce again equalize when viewed in relief. However, this sedimentation would increase themass of the crust in the two troughs, thereby increasing their weight even withoutsignificantly increasing their vertical depth, which would further exacerbate the isostaticeffect, i.e. the glacier with its surrounding container of packed sediment would continue tosink to the maximum limit allowed by the rigidity of the crust, as would the land beyond thebulge, which would cause the crust forming said bulge to continue to rise and be eroded, justas before. As the bulge continued to lift, the asthenosphere would follow and harden as itneared the surface. This is the same balance struck by mountains, whose roots extend far intothe mantle, and which may remain at a constant height for 100 kyr’s despite the forces ofweathering and erosion (Peltier 111). This seems to imply that when there is weightsuperimposed on the planet’s surface, creating an isostatic effect, it is the forces of erosionand sedimentation, rather than the forces of lithospheric rigidity v. elasticity, that create theillusion of equilibrium (i.e., land around a glacier appearing to be level). True equalization of
  14. 14. Zans 5the crust is not restored in such a case until the mass is removed, as happens eventually tomountains due to erosion and to glaciers as they melt. Water in it’s liquid form is just as dense as ice, so there is an isostatic adjustmentinvolved in the melting and freezing of water on a global scale and the oscillation of sea levelthat follows, which is called ‘eustasy’. The two are inextricably tied, but the finer interplaybetween ocean loading/basin size and glacial mass/isostasy is unclear. Data on their synchronicity feeds directly into the field of paleoclimatology, however,demonstrating the interrelationship between global phenomena. Data on glacial isostasy hasbeen used to facilitate the research and support the conclusions of innumerable researchers inmany other fields considered to be ‘unrelated’ to glaciology. One such realm is the study ofGlobal Isostatic Adjustment (GIA), which is “the global process… whereby the Earth’s shapeand gravitational field are modified in response to the large scale changes in surface massload that have attended the glaciation and deglaciation of the planetary surface” (“GlacialIsostatic Adjustment; A Survey of Recent Studies”). It is unclear how exactly the shifting ofmass affects the planet’s gravitational field, and what further affect this would have on thelocation of ice mass, the behavior tectonic plates, the distribution of ecosystems, etc., but allof these phenomena are obviously part of an incredibly complex chain of feedback loops. Isostatic data can also be used in models depicting other aspects of global history.With said data and additional information on the planet’s viscosity, and as well as parametersfor prehistoric ice sheets, models can be developed that describe “the deformation of the ofthe entire planet, that distribute the meltwater in a self-consistent way into time-dependentand realistic ocean basins, and that include the effects of the changing water load as well asice load” (Gornitz 375). In fact, scientists have only arrived at their present understanding ofthe earth’s viscosity thanks to the observable deformation of the planet’s surface due toglacial isostasy: “one of the primary motivations for studying the uplift of formerly glaciated
  15. 15. Zans 6regions such as North America is to deduce a radial structure and viscosity profile of theinner earth. The disappearance of ice and subsequent isostatic response recorded as changesin relative sea level at coastal locations is one of a limited set of phenomena that allowinvestigation of the earth at depth” (Zweck 321). Glacial isostasy is particularly suited forscrutiny since it acts on a scale of thousands, rather than tens or hundreds of thousands ofyears. There is, however, no model that can include the world’s complexities, so models mustbe assumed to give skewed or uncertain results. This component of uncertainty, and the inability of models to predict the future oreven accurately portray the past, has made understanding the effect anthropogenic globalwarming will have on the glaciers in terms of isostasy even more difficult. It is known thatinter-intraglacial cycles run in spans of approximately 100kyr, that the “Last GlacialMaximum” occurred between 19-30kyr years ago, and that since that time approximately50x166 km3 of ice has melted, “leading to a rise in global sea level of ~130m” (Shum, Kuo,and Guo (?) 149). Whatever the cause of the present intraglacial period, it is clear that anthropogenicfactors are behind the present “global warming” phenomenon, which is raising bothatmospheric and oceanic temperatures. This has exacerbated the melting of both the Antarcticand Greenland ice sheets, contributing to an estimated rise of average sea levels by between1.5 and 2.0 mm/year (Shum et al). Since global warming is not likely to abate, it is likely thatglacial melt will also continue, at a continuously accelerating rate. This acceleration has already been observed. In 2008 an international team ofscientists “estimated changes in Antartica’s ice mass between 1996 and 2006 and mappedpatterns of ice loss on a glacier by glacier basis. They detected a sharp jump in Antarctica’sice loss, from enough ice to raise sea level by 0.3 millimeters (.01 inches) a year in 1996, to0.5 millimeters (.02 inches) a year in 2006” (“Antarctica Ice Loss Speeds Up”). Also in 2006,
  16. 16. Zans 7a team of researchers at UC-Boulder “used data from a pair of NASA satellites orbiting earthin tandem to determine that the Antarctic ice sheet… is loosing up to 36 cubic miles of ice, or152 [km3]” (“Antarctic Ice Sheet Loosing Mass”) out of it’s 14 million km2 total, on anannual basis. In terms of eustatic change, the complete melting of the Antarctic sheet, whichas of 2008 contained about 90% of the world’s ice and 70% of it’s fresh water, would raisethe global sea-level by 56.6 m, while complete melting of the Greenland sheet would raisethe global sea level by 7.3 m (Shum et al). This is theoretically within the realm ofpossibility, at least for the Greenland sheet during the summer months, but it is not yet knownwhether the Antarctic sheet could ever melt completely. Neither is it known what sort of effect the tectonic rebound following such a severemelting of the remaining polar ice would have, how severe it would be, or how soon theeffects would be seen. This uncertainty is largely due to the fact that: a. the future severity ofglobal warming is difficult, if not impossible, to predict; b. the thickness of the crust beneaththe remaining glaciers and ice sheets is not well documented; and c. that even the viscosity ofthe mantle beneath is not yet completely understood. These three factors, in addition to aplethora of others, make modeling future isostasy difficult. There are, however, a few researchers doing work related to the subject. In 2000 Wuand Johnston studied the likelihood of rebound-related earthquakes in the North Americancontinent, after they noticed that despite the fact that the area “east of the Rocky MountainCordillera is supposedly a stable continental region… it experiences intraplate earthquakeswith magnitude as high as M8” (Wu and Johnston 323). They site a previous study done byresearchers in 1996 which found that “intraplate earthquakes in Eastern Canada,” again, asupposedly tectonically stable region, “may be a consequence of tectonic forces andpostglacial rebound stress,” largely due to “past tectonic processes [which] created weakenedzones where faults, brought close to failure by the current tectonic stresses, may be

  19. 19. Zans 1Erin Collier-ZansDouglas DuperENV20713/12/10 Greens: The Role of Diversity in the Formation of the German Green Party, 1970s-80s In many movements, there has been a strong dynamic between people of different agegroups and worldviews. In many cases, this dynamic is antagonistic and counterproductive.The young demographic is often more radical and craves sweeping reform, while the olderdemographic is usually more inclined to try to work within the existing, familiar system tocreate less drastic changes than those craved by the young. Within any movement, it followsthat there will also be disagreement about what the focus should be. Should a so-called“Environmental” movement focus solely on issues of environmental health and preservation,or should it be flexible enough to include clean energy, citizen health, women’s andminority’s rights, anti-nuclear, peace and social reform movements among others, in additionto environmental concerns. Is seeking to accommodate a diverse electorate with an array ofideals and agendas ‘unacceptable compromise’ on the issues, or is it a success in its ownright? In Germany, the modern Alliance ‘90/The Greens has gained significant support,winning almost 11% of the votes in Germany’s last election cycle. But how did a series ofsmall, diverse groups and movements in Germany coalesce to form the modern Green Party,and how did this group manage to gain such a foothold in national and even EU-level politicswhen many other nations’ Green Parties struggle to gain even municipal-level success? The diversity of the German Greens, the party’s historic acceptance of diverseviewpoints and outspokenness on a wide range of issues, all under the banner of “TheGreens,” has been a major contributor to its success. It has gained popular support thanks tothe fact that it does not radicalize its membership and voter base into “Environmentalists” and“Non-environmentalists,” remaining unspecialized and inclusive of many ‘alternative’ issuesand agendas. The evolution of the German Green Party, or die Grünen, is considered to have reallybegun in the early 1970s with the formation of as many as several thousand “‘citizeninitiatives’,” which were fragmented and entirely local movements seeking to address very
  20. 20. Zans 2specific issues, like the establishment of a particular nuclear power plant or the need forgreater democracy in a workplace (Longguth 6). Soon, however, initiatives with commongoals began looking for support in the greater community and many became part of one ofmany umbrella associations, such as the Federal Association of Citizen Initiatives for theProtection of the Environment, to which over 300,000 people and over 1000 local citizeninitiatives were affiliated by 1977 (7). According to Longguth, this was the ‘first phase’ of the Greens’ development. Thebackbone of environmental initiatives in this period was confronting the proliferation ofnuclear power stations after the Cold War rather than the severe environmental degradationdriving movements in the United States and even other parts of Europe(clarify/split up).Germany did not have as great an issue with environmental safety concerns prevalent in othernations due to the fact that, according to Shull, “Germany had had a fairly enlightened policytoward the environment as early as the nineteenth century, when preunification GermanLander and private business associations regulated water and air pollution… After [WWII], apremium on strict adherence to legal principles set by the institutions of the Federal Republic[had] fostered precautionary and preventative attitudes toward potential environmentalhazards” (12). This is in stark contrast to the policies of the United States in the 20th centuryonward, which focused on remediation and cleanup after severe damage to the land hadalready been committed and the danger recognized, rather than focusing on avoiding suchdamage in the first place. (good point) Thus began the second ‘phase,’ with the above-mentioned consolidation of manyfragmented movements and ideologies into voter initiatives. These manifested in the form of‘Green’, i.e. ecologically-minded, and ‘Rainbow’, i.e. social-reformist ‘Lists’, whichproceeded to run in various elections, but which failed to gain the requisite 5% of the nationalvote in order to send deputies to the Bundestag, or German parliament (Longguth 9). Thesecollaborative organizations continued to gain support, but it was those such as the “RainbowList/Defend Yourself!” and “Alternative List for Democracy and Environmental Protection”which gained more traction than more conservative, single-issue groups such as the strictlyecological GLU (Green List for the Protection of the Environment) and later the GAZ (GreenAction Future). These unaccommodating groups were especially unappealing to the youngerportion of the populace, and in 1977 the GLU received only 2.4% of the 18-24 demographicsvote, which conversely gave a large portion of their support (18.2% nationally) to RainbowList in that same year (9). It has been suggested that blue-collar workers and others were themost important and therefore target demographics for alternative parties, including the early
  21. 21. Zans 3Greens, in 20th century Germany (Shull 26-27), but at least in this country the importance ofthe younger voters is easy to see, and for a party to have any staying power it must have someway to continue to capture the imagination, hopes, and loyalties of students and youngprofessionals if it is to remain viable in the long-term(split up long sentences). These consolidated second-phase groups brought together a wide range of interestsand issues, from the perceived failings of the democratic system, to the oil shocks of the 70sand the waning appeal and gradual collapse of a ‘progress’-model economy, to women’s,worker’s, and gay rights, and anti-nuclear/anti-war protest initiatives (Shull 31). The mostsuccessful managed to maintain this diversity into the late 1970s-early 80s, when the ‘thirdphase’ began with the founding of SPV-The Greens, in 1979. This group was specificallyaimed at carrying the ideals of the early protest movements forward into the establishedpolitical arena, something that has been viewed alternatively as a wise and effective choiceand as a betrayal of the group’s own ideals. SPV-tG was composed of both conservativeecological groups like the GLU and the GAZ (‘the Greens’) and a variety of other initiativesof vital importance to many, more liberally-minded social reformists (‘SPV’ – Other PoliticalAssociations). The fourth phase of the German Greens’ development arrived with this group’s firstconvention, held in 1980, when their first platform was drafted, addressing everything fromabortion and women’s rights, to economic reform and the alleviation of unemployment, toissues regarding the environment and its protection. The Greens achieved several regionalsuccesses, but national success would not come until the ‘fifth phase’ when, in 1983, theGreens received more than the requisite 5% of the national vote and were able to send 27delegates to the Bundestag and 7 to the European Parliament. Their message was clearlystated: they promised to represent “the interests of all who are affected by the policies of theEuropean Community but not represented in it” (qtd in Longguth 16). Several like-mindedgroups in the EU parliament soon banded together to form the ‘Rainbow Faction’, with theobvious intention of carrying forward the established precedent among ‘Green’ groups ofadvocating for many issues not commonly addressed by their more conservative politicalcounterparts. The ‘fifth phase’ of the 1980s, the end of our review of the Greens’ historicalbackground, was marked by “increasing skepticism… by a portion of [SPV-The Greens’]voter membership due to and about increasing parliamentary participation, with bothestablished governments and radical groups feeling the party [had] been compromised by‘extremists’,” with a major point of contention being their past and possible future
  22. 22. Zans 4involvement with the socialist SPD (Social Democratic Party of Germany), and other similarorganizations. This led to fragmentation within the party between liberals (mostly younger,more radical) and conservatives (mostly older, wealthier, strictly ecologically-minded), andalso along the lines of major philosophical affiliations, largely among the “(i) eco-libertarians”, who believed that market forces were the answer, “(ii) realists”, or thoseencouraging political alliance and negotiation, “(iii) fundamentalists,” the eco-conservativesmentioned above, and the “(iv) eco-socialists”, or those who “insisted on the interrelationshipof social and ecological questions and the need to oppose the capitalist state” (Weisenthal11). Some of the more conservative members of the party left to form the ÖDP(Democratic Ecological Party), but like its predecessors the GLU and GAZ, it failed toachieve much traction and as of the late 1980s had not managed to gain official party statusby claiming the requisite 5% of the vote. The Greens struggled for a while in this period, butmanaged to stay intact and after another trying couple of decades, is now taking between 8and 12% of the German vote in each of the most recent years’ election cycles. The Green party emerged from and rode the wave of post-industrial/Cold Wardisillusionment and subsequent strife prevalent in 1970s Germany, which sparked a nationalmovement seeking generally to create a ‘new’ civilization out of the old. The Green Partyarrived on the scene as a distillation of these various movements, first into “Lists” or nationalelectorates sharing the same general interests and goals for the future, and then into its ownself-identifying ‘Party’. (if you are paraphrasing, be sure to include sources) It was supported by a vast array of peoples rather than by a small, single-minded,issue-centric and loyal demographic. Internal conflicts in the party really only became aproblem not after unification, but after their initial success in 1983 when, as a natural steptowards ‘partydom’, various representatives sat down and tried to finalize the groups’platform and thereby define what exactly the focus and main issues of the party would be. They were trying to honor the ‘roots’ of this party, but there was disagreement overwhat exactly this meant. Would they side with their supporters in workers unions seekingeconomic reform? Would they side with radical anti-nuclear activists seeking energy reformand greater self-dependence for Germany as a nation? Or would they focus solely on issuesof the environment, and thereby further disenfranchise those of their supporters most keen onaddressing other issues? There is, in any political party, a choice to be made between ‘efficacy’ and ‘identity’,or diversity v. focus. On the one side, a party may “press intense, often nonnegotiable
  23. 23. Zans 5demands for change,” which with their specific goals have a chancge of achieving greatsuccess, but which also “[conflict] with the guarantee of diversity… or the continuation of theorganization itself” if it fails to capture a significant proportion of its target electorate. Theobvious alternative, then, is a strategy of diversity, which means “articulating the demands ofa range of social movements… By expanding the scope of issues addressed, the aim is torally the broadest possible base of supporters” (Shull 45). If the former path is taken, the “electoral support may be deep (that is, reliable), butnot wide (that is, extensive in members)… [and] to maintain credibility with its base, theparty has to keep up the intensity and momentum of demands for change” (46). This focus onone issue and on appealing to a single worldview “often implies deferring actual movement –that is, obtaining tangible gains – in the name of guaranteeing the authenticity and purity ofthe mobilizing ideals of the supporting social movement” (46). This dynamic was clearly seen with the Green Party throughout the 70s and 80s.Critics of SPV-The Greens often claimed that they had made just such a sacrifice of ‘purity’,that they were ‘betraying’ the ideals even of those who had rallied to create and support it byassociating with other groups and especially with the SPD and FDP. On the other side,however, were those groups such as the ÖDP and GAZ which sought to maintain‘authenticity’ by focusing only on ecological issues, and which summarily failed to gain anyquantifiable success. Some may believe that taking on social and other issues in tandem with problems ofenvironmental endangerment is somehow compromising the effectiveness and inherent worthof the ‘Environmental Movement’. By this logic, the Rainbow List/Defend Yourself!, itsdescendent SPV-The Greens, as well as the ‘Rainbow Faction’ of the 1980s EU Parliamentwere all failures, despite all evidence to the contrary. They may have made accomplishmentson the ecological and related anti-nuclear fronts, but these accomplishments were already‘tainted’ due to their simultaneous outspokenness on problems of social inequality, etc,because their focus was diluted. But which is better: effectiveness, or ‘purity’? When considering the downrightfailure of dedicated environmental groups in 20th century Germany to achieve any lasting,national-level changes, would it not be better for environmental reform to arrive even as afootnote of more conservative policies continuing the established, ‘corrupt’ system, than tohave this reform not arrive at all due to the over-dependence on over-identified politicalparties such as many of the modern-day “Greens”.
  24. 24. Zans 6 It is better to achieve widespread, diluted change by garnering support fromwidespread, diverse interest groups than to fetter the movement from the start by remainingsingularly focused on any one issue.. Who is to say that peace movements, women’s andminorities rights movements, democratic labor movements, etc., have no place in movementsconcerned with the ‘environment’. If people and their actions are going to be acknowledgedas being the ‘problem’, then surely people are the answer, and to succeed people, from allwalks of life, seeking a better world through many avenues, must be included in the solution.If social reform is the goal, then the historic development of die Grünen has a lot to teach us.The Greens Party of Germany, after all, “might justly be regarded as the finest achievementof the second wave of environmentalism, referred to by the respectful capital that sets it apartfrom its peers and contemporaries: the Greens, as distinct from all other kinds of greens”(Guha 97). A solidly presented and researched paper—you do a very good job of tracing thedevelopment of the Greens in Germany. It might be interesting to consider how theirapproach could be adapted (or if it could be) to U.S. politics, and if so, what would strategylook like?

  25. 25. Zans 7 Final Question:Reflect upon the history of the environmental movement since the “second wave,”that began in America about 50 years ago with Silent Spring. Have your ideas aboutenvironmentalism changed or deepened? If so, how? What practices, theories, or peopleof the environmental movement in this time period have resonated with you and why?What do you think are the successes and most effective solutions offered by this waveof environmentalism? What are its failures and weaknesses? Finally, project yourthinking from the past to the future, remembering that “those who don’t understandthe past are destined to repeat it,” as a philosopher once said. What would be effectiveenvironmentalism for the future? Support your answer with plenty of support from thereadings after the midterm. There were several, very important concepts that stuck with me from this portion ofthe semester, but for the sake of time and space, and because many of the readings have beenremoved from the e-reserves(I emailed them most likely), I will only speak on one at the riskof failing miserably at this assignment This one, strongest issue for me, which has in a way overridden other concerns, is theinvolvement of women and minority groups in ‘environmentalism’, and the issues of socialjustice that inevitably follow and become incorporated. It might be good here to look at the ‘environmentalism of the poor’, of which there aremany examples, each soundly disproving the unfortunately yet prevalent misconception that“environmentalism is a phenomenon peculiar to the rich nations of the North, a product of themove toward ‘postmaterialist’ values among the populations of North America and WesternEurope” (Guha 98), a presupposition that leads to the horrible conclusion that for‘environmentalism’ to take hold in the rest of the world, the world’s poor must first bebrought up to first world-identical living standards, something that various countries andgroups have been trying, often unsuccessfully, to accomplish, probably since the end of theColonial era. I suppose that we might need a new word for what is being practiced in the so-called‘third world’, because it certainly doesn’t look like most environmentalism in this and otherrich countries. The environmentalism of the poor is often, on some level, driven by theeconomic deprivation created by local environmental degradation (105). The livelihoods ofcommunities are routinely threatened by first-world economic ventures like mining and clear-cutting, and their form of ‘environmentalism’ is driven at least partially by true, humandesperation. Without the forest, how would they live? Without clean streams, what will theydrink?
  26. 26. Zans 8 Along with any spiritual or cultural associations/factors, these are true needs. They areimmediate, and cannot be forgotten or looked over, unlike the oil spill or Katrina for peoplein the US not living on the coast, or strip mining for people not living in the Appalachians,etc. It seems to me that a significant portion of modern ‘first-world’ environmentalist action,stemming from any number of complicated and unquantifiable emotional/logical attachments,tends toward detachment or inefficiency, while the environmentalism of the poor, beingattached as it is to an “often more visible concern for social justice” (105) involves blood,sweat, and tears because they are true movements of the kind we haven’t seen on a nationallevel since the 1970s feminist movement, itself growing out of the 70-some year struggle forcivil rights and the 100-odd year struggle for women’s votes. I feel it might be a good time to bring in the possible ‘death of environmentalism’.The authors of The Soul of Environmentalism say, “in the ‘90s, the declaration that “poetry isdead” was an attempt to deny and marginalize a rich array of new anti-establishment forms ofpoetry. Back then, the writers ignored rap, performance art, and poetry slams. The debateover “The Death of Environmentalism” feels like a similar exercise in its omissions” (6).They go on to point out that “environmentalism and other progressive movements in theUnited States are not dead, but they are crippled by denial… [Yet] environmentalism, likepoetry, has a soul deeper and more eternal than the one described by its examiners. It’s a soultied deeply to human rights and social justice, and this tie has been nurtured by theEnvironmental Justice and Sustainability movements for the past 20 years” (6).(goodsupporting quote) Perhaps the soul of environmentalism can be seen in the paradigms of‘environmentalism for the poor’. This is not to say that the soul is only here – I at least havethe unfortunate habit of associating soul with ‘one’, and thinking that the soul can only be in‘one’. But the soul is a web. Soul is a verb. The soul is the network of information, energy,activism, art, tradition, everything that makes us quintessentially human. Now, a bit of a jump, to wrap up: Why is this important?, I have been asking myself.Is the history of the environmental movement and its future important to me as a detachedobserver? Is it important to me, as a future activist? I think the latter is truer, but that raises allsorts of other questions that I have been grappling with for a year now. Is my attempting tobecome involved in ‘environmentalism for the poor’ a continuation of the unfortunate WhiteKnight syndrome, whereby wealthy people feel obligated to get involved not out of a realsense of purpose or belief, but out of guilt, or out of a mistaken and idealistic perception that‘other is better’? And how could I possibly get involved without being perceived as an
  27. 27. Zans 9ambassador for the Western model of my origin, merely by showing up? Should I even getinvolved abroad? If the problems have been largely caused by the actions of first-worldnations, shouldn’t I stay in my own country and spend a significant portion of my life tryingto do something from here? But then I remembered the early months of the Democratic Movement in China.Westerners, educators and participants in the civil rights/anti-war protest movements wentthere to teach successful models of nonviolence, not because they believed their models were‘better’ or their audiences ‘ignorant’ but because activists in that country requested that theycome and share information and experience. These educators, then, were serving the commongood and the good of those they were teaching by being there. They were serving, notenforcing. So, I guess that my personal model of ‘environmentalism for the future’ is focusing onpreserving human-ecological diversity. If we are animals, and we are not separate, then weshould not be separate and the preservation of unique cultures should go hand in hand withthe preservation of biodiversity. In the end, I’m only going to live a few more decades and Ishould do what I feel best about, knowing that whatever change I manage to make happen isa drop in the ocean, and while not necessarily unimportant, certainly miniscule. Change is forall generations. Humanity is a work in process, and giving the present a sort of ‘calm beforethe storm’ feeling associated with the perception of the future as the coming apocalypse, isn’tparticularly helpful in my mind. I have no idea what the grand picture of future environmentalism ‘should’ look like. Ican only hope that it is more diverse and vibrant than what we have now, with less emphasison individual and personality (unless we find a useful rallying point like Gandhi or MLK),and that it will be lead by the humble and the sincere. I hope that, if necessary, the world willleave the US behind and stop waiting for it to lead the way into this more environmentallyfriendly future – something that it is quite probably incapable of, at this point. In the end, Ihave hope. What else can I do? A thoughtful response that grounds your study of the class topics with your personalmotives.

  28. 28. Introduction to High School Course Work 2006-2008 For this portfolio I have also provided a selection of my high school work, fromsophomore through senior year. I have chosen pieces that I believe exemplify my capabilities as a writer during thatperiod, in the core subject areas. Teacher comments have been included where available, andrubrics with final grades are also attached to the end of each document. These rubrics arethemselves valuable, in that they give a clear idea of the standards to which RMSEL held itsstudents; the grades I received for these pieces demonstrate the standards to which I held myself. I have provided two pieces from Science: one is a write-up for a dissection lab my classdid sophomore year, while the other is the final product for an expedition we did on weatherpatterns (and data sets), global warming, and research skills. I have also provided two math write-ups. The first relates to our senior-year expedition inexpressing exponential growth; in my own words from 2008, “there were other write-ups thatperhaps demonstrated my capabilities as a math student better, but his piece showcases myability to work in generalizations and abstractions (of which I am very proud), to go above andbeyond the requirements of an assignment, and to connect statistics reality and especially to[the] humanitarian issues we will be facing in the future.” The second, entitled simply ‘OrchardWrite-up,’ I wrote at the conclusion of an expedition on geometry and angles. My favouriteelement in both expeditions was generating generalized formulae to express the entirety of thatsemester’s work – I enjoy working, as mentioned before, in abstractions, and I find formulasboth elegant and beautiful; they are art. Rather than present yet another investigative piece to exemplify myself as a ‘Humanities’student (Humanities being the subject encompassing sociology, history, mythology, etc), I haveinstead chosen to provide 2008’s best attempt at creative writing – a piece entitled ‘FreedomsThat Be,’ a modern-day interpretation of the myth of Daphne, a nymph. As I said in 2008, “This subject [i.e. art and myth] is very personal to me; I can paint and draw quite well, and have often been asked, ‘why don’t you want to become an artist?’ I answer this question in my myth by creating a [character] who did become an artist, and suffered for this choice… Art is very personal [for] me, and I am very proud of this myth; I consider it a work of art unto itself. Perhaps that is why I worked so hard on it, and picked over it again and again in an attempt to make it perfect, [which] demonstrates another of my personality traits: perfectionism and an unwillingness to just let something go. This trait doesn’t serve me well when I’m making a painting, but I believe that the quality of my myth benefited greatly from an extensive drafting process.” Finally, ‘Un Barco se Hundio’ is an example from 2007 of the sort of work we often didin Spanish class. It was a fun, interactive class – we got up on chairs and tables and danced, puton costumes and enacted plays, in order to enact the vocabulary we were learning. We also wrotelittle stories like this one, often with animal characters in silly circumstances, again usingwhatever vocabulary words the teacher opted to require. My study of verb conjugation duringmy time in Quetzaltenango, Guatemala in 2006 helped a great deal with this piece.
  29. 29. -Notice that the main difference between the cephalothorax and the abdomen is the segmented nature of the former. The thorax bends and is used to move the animal about, while the cephalathorac is a hard shell, protecting the animals head and many of its internal organs. The crayfish’s exterior is not similar to that of a human, as they have exoskeletons, while we have an internal skeleton.3. Turn the crayfish on its side, and locate the rostrum, which is the pointed extension ofthe carapace at the head of the animal shown in the diagram above. Beneath the rostrumlocate the two eyes. Notice that each eye is at the end of a stalk. Diagram observations onobservation sheet.4. Locate the five pairs of appendages on the head region. First locate the antennules inthe most anterior segment. Behind them observe the much longer pair of antennae.Diagram observations on a new observation sheet. -Is is advised that you keep the animal on it’s side for this part of the study, because the appendages of the head are best viewed from this angle.5. Locate the mouth. Then observe the mandibles, or true jaws, behind the antennae. Nowlocate the two pairs of maxillae, which are the last appendages in the cephalic region.Diagram observations. --The appendages related to the eating of food are the maxillipeds, of which there are three pairs. They all hold food, tear it up, and pass it into the mouth, where the mandibles crush it. The second pair of maxillipeds are also used for passing water over the gills. They operate in a similar fashion as our hands, or fingers, tearing food up and passing it to our own mouths, however our arms are also similar to the chelipeds, or claws.6. On the thoracic portion of the cephalothorax, observe the three pointed maxillipeds.Diagram.
  30. 30. 7. Next observe the largest prominent pair of appendages, the chelipeds, or claws. Behindthe chelipeds locate the four pairs of walking legs, one pair on each segment. Diagram.8. Now use the walking legs to determine the sex of your specimen. Locate the base segment of each pair of walking legs. The base segment is where the leg attaches to thebody. Use a magnifying glass to study the inside surface of the base segment of the thirdpair of walking legs. If you observe a crescent-shaped slit, you have located a genitalpore of a female. In a male, the sperm duct openings are on the base segment of thefourth pair of walking legs. Use a magnifying glass to observe the opening of a genitalpore. Diagram. -This specemin was a male. The external reproductive organs of the crayfish are not similar to humans, as male humans have a protruding reproductive organ, while both sexes of the crayfish have ducts used to transport eggs and sperm to the outside.Exchange your specimen with a nearby classmate who has a crayfish of the opposite sex.Then study its genital pores. Diagram!9. On the abdomen, observe the six distinct segments. On each of the first five segments,observe a pair of swimmerets. Diagram.10. On the last abdominal segment, observe a pair of pointed appendages modified into apair of uropods. In the middle of the uropods, locate the triangular-shaped telson.Diagram.11. Now turn the crayfish ventral side up. Observe the location of each pair ofappendages from the ventral side. Diagram -Notice that the appendages can be better viewed from the ventral side, as when the animal is on its dorsal side, the area where the limbs are attached to the body is hidden, as are the swimmerets.12. Next you will study the internal anatomy of a crayfish. If you must store yourspecimen until the next lab period, cover it with a dampened paper towel. Then place thespecimen on the tray in a plastic bag. Close the bag with a twist tie. Write your name onthe bag with a felt-tip marking pen, and give your specimen to your teacher.13. Clean up your work area and wash your hands before leaving the lab.Consult with a member from an earthworm dissection group, and create a table ofsimilarities and differences between your two specimens: Similarities Differences Both segmented animals Worms reproduce using the clitellum

Earthworms fertilize eggs externally.Crayfish are more advanced because they have a more developed respiratory system.Oxygen, in worms, in transferred directly to the circulatory system by its soft skin, whilethe Crayfish passes water over its gills, taking the oxygen from the water, and thentransferring it to the circulatory system (?). The pores on the exterior of the earthwormabsorb oxygen but if the animal is put into water, it will drown. However, when thecrayfish is put on land for an extended period of time, it suffocates, as its gills cannotfunction as lungs do, and it must be in water to breath. Therefor, each animal has evolvedto function in specific environments. The earthworm thrives in loam, and other nutrientrich soil. The crayfish inhabits most freshwater bodies, though it seems to be common instreams, rivers, and ponds. Its relative, the lobster, lives in saltwater.Part 2- Internal Dissection:14. Put on a lab apron and gloves.15. Using one hand to hold the crayfish dorsal side up in the dissecting tray, use scissorsto carefully cut through the back of the carapace along dissection cut line 1 as shown inthe diagram below. Cut along the indentations that separate the thoracic portion of thecarapace into three regions. Start the cut at the posterior edges of the carapace, andextend it along both sides in the cephalic region.
  32. 32. 37 16. Use forceps to carefully lift away the carapace. Be careful not to pull the carapace away too quickly. Such action would disturb or tear the underlying structures. 17. Place the specimen on its side, with the head facing left, as shown in the diagram below. Using scissors, start cutting at the base of cut line 1. Cut along the side of the crayfish, as illustrated by cut line 2. Extend the cut line forward toward the rostrum (at the top of the head). 18. Use forceps to carefully lift away the remaining parts of the carapace, exposing the underlying gills and other organs. 19. Use the diagram below to locate and identify the organs of the digestive system. Locate the maxillae that pass the pieces of food into the mouth. The food travels down the short esophagus into the stomach. Locate the digestive gland, which produces digestive substances and from which the absorption of nutrients occurs. Undigested material passes into the intestine. Observe that the intestine is attached to the lobed stomach. The undigested material is eliminated from the anus. -The teeth on the inside of the stomach are used in grinding up the food, after it is torn up and passed to the mouth by the maxillipeds. Muscles on either side of the stomach are used to contract and move the stomach about. 20. Use the diagram below to locate and identify the organs of the respiratory system. Locate the gills, which are featherlike structures found underneath the carapace and attached to the chelipeds and walking legs. A constant flow of blood to the gills releases carbon dioxide and picks up oxygen.
  33. 33. -The gills have a very large surface area for greater oxygen absorption. This is similar to human lungs. A person with larger lungs will absorb more oxygen that someone with smaller lungs.21. Use the diagram of the internal anatomy of the crayfish to locate and identify theorgans of the circulatory system. Locate the dorsal tubular heart and several arteries. Thecrayfish has an open circulatory system in which the blood flows from arteries intosinuses, or spaces, in tissues. The blood flows over the gills before returning to the heart.22. Use the same diagram to locate and identify the organs of the nervous system. Findthe ventral nerve cord. Locate a ganglion, one of the enlargements of the ventral nervecord. Locate the dorsal brain, which is located just behind the compound eyes. Note thetwo large nerves that lead from the brain, around the esophagus, and join the ventralnerve cord. -Many nerves leave from the ganglion, and are used to activate the swimmerets.23. Use the same diagram to locate and identify the organs of the excretory system. Theblood carries cellular wastes to the disk-like green glands. Locate these organs just infront of the stomach. The green glands excrete waste through pores at the base of eachantenna. -The green glands secrete excess water and ammonia. In this, they are similar to the bladder, storing wastes, and then removing them from the body.24. Use the diagram once again to locate and identify the organs of the reproductivesystem. The animal shown in the diagram is a male crayfish. If your specimen is a male,locate the testis. The testis is the long, white organ under the heart and a bit forward. Thesperm ducts that carry sperm from the testis open at the fifth walking leg. If yourspecimen is a female, locate the bi-lobed ovary. It is in the same relative position as thetestis, but the ovary appears as a large, reddish mass under the heart. Then locate theshort oviducts that extend from near the center of each side of the ovary and open at the
  34. 34. third walking leg. Exchange your specimen with a nearby classmate who has a crayfishof the opposite sex. Then study its reproductive system.25. Dispose of your materials according to the directions from your teacher.26. Clean up your work area and wash your hands before leaving the lab.Conclusion:The hypothesis proved to be true. Humans and crayfish are both motile animals, andshare many of the same internal structures, such as: organs used for breathing (thoughboth are adapted to their environment, lungs vs. gills), stomach, intestine (and a similarway of absorbing nutrients, breaking down the food in the stomach, then absorbingnutrients through the intestine, into the bloodstream). Both have appendages capable ofgrasping things, in humans, it is the opposable thumb, in crayfish, the chellipeds.However, the skeletons of these two creatures are very different. The crayfish has anexoskeleton, which it must shed periodically in order to grow, while the human has aninternal skeleton, and stops growing after a certain point. There are other dissimilarsystems, such as the maxillipeds. There are no similar structures in humans. Humans usetheir fingers to grasp food while it is put in the mouth, then teeth to grind and tear it intodigestible pieces. In conclusion, excepting a few differences, crayfish and humans areincredibly similar.Diagrams:Observations Inferences

  39. 39. Erin Collier-Zans2007 Global Warming and Disease Outbreaks in Colorado and China Is the climate changing? Few scientists would deny that something drastic is going on.This century has seen a global increase in average temperatures by between .7 and 1.5° F. Theburning of fossil fuels has released aerosols into the atmosphere, which capture and retain heat,hence the greenhouse effect. The sea ice is retreating, causing the sea levels to rise. Sea-surfacetemperature warming is causing more severe and frequent hurricanes, cyclones, and typhoons.Desertification and floods plague non-coastal areas. Is global warming to blame? Are we toblame? Does global warming really affect us, and what can we do to make positive changes?Hypothesis: The average temperature and precipitation for the month of August, collected by weatherstations around Colorado, and the RMSEL weather station, will show a general warming/risingtrend, for the period between 1950 and the present day.Data from Colorado weather stations: Average High Temperature for the State of Colorado In the Month of August By Year 70 69.5 69 68.5 68 Temperature (°F) 67.5 67 66.5 Average High Temp. 66 65.5 Expon.

Thishigher humidity and temperature in turn causes the outbreak of deadly tropical diseases, likemalaria and West Nile Encephalitis, which pose a serious threat to human health both locally andglobally. In the summer of 1998, China suffered a massive flooding of the Yangtze River, theworst in 44 years.1 It had been an unusually wet rainy season, leading to extremely high waterlevels in lakes and rivers. This resulted in 7 consecutive flood surges, 3 of which occurred withina span of 3 days. It was suggested to the Chinese government that the flood might be diverted, but insteadof paying heed to this suggestion, the government decided that the bank of the river should besecured instead. To aid in the accomplishment of this, the government “instructed that authoritiesat all levels increase material and manpower to secure the bank at all costs. According to theMinistry of Water Resources data, materials and supplies worth more than 10 billion Yuan(US$1.2 billion) were expended on the situation.”21 http://edition.cnn.com/WORLD/asiapcf/9808/25/china.floods.01/2 http://www.theepochtimes.com/news/4-12-27/25263.html
  42. 42. 4 The first levee to collapse was in Waijiang, Hezhen of Jiayu County. It collapsed onAugust 1, after which soldiers and rural workers from the area worked nonstop for five days andnights, attempting to block the hole. Finally, the strategy of sinking of ships and trucks andfixing wooden boards succeeded. On August 5th, the levees in Paizhou, Jiujiang, and Jiangxin area of Jiayu Countycollapsed. This area was densely populated, mostly around the Paizhou area, which wasinhabited by some 500,000 people. Almost all the able bodied were out working, tryingdesperately to block the flow of the river, but to no avail. The levee collapsed completely atmidnight, engulfing about 100 soldiers, locals, and policemen who were working on the dam.The river swept into the villages all along the riverbanks, flooding homes, schools, andfarmlands. The sleeping children, women, and elderly didn’t stand a chance. They had receivedno forewarning, and 11,000 died. A further 1,000 laborers were declared missing, presumablyswept away by the flood crest. During the rest of the day, the lower reaches of the river flooded, collapsing more leveesin Jiujiang and Jiangxinzhou. The main Yangtze levee collapsed on the 7th, at which point thegovernment grew desperate, and ordered that any and everything that would pack down bethrown into the river, to block the hole. 5 million tons of rice, soybeans and other grains werethrown in, along with some 50 trucks and 18 ships. A unit of 200 soldiers specially trained to handle flood disasters was dispatched fromZhangjiakou, who filled the hole with concrete and boards, finally blocking the hole and stopping the flood. 12,000 people were claimed by the river upstream, around 6,000 people died in the rivers’ lower reaches, and the series of levee collapses amounted to some 58 billion yuan, or around 7 billion US dollars in damages. On top of that, around 14 million people were displaced. Many had no homes to return to, once the floodwaters had subsided. A soldier helps an elderly flood victim The Yangtze River area contains a boomingeconomy, and people were quickly moving into the river basin. The fertile lands around the rivercontain about 3% of the countries total farm land, the erosion and inaccessibility of which
  43. 43. 5drastically affected the health of the countries economy since China at the time contained 1/5 ofthe worlds human population and only 7% of its arable land. The hardships faced by the survivors continued, without relief. Many remained shelter-less. Those who returned to the flooded areas were plagued by a multitude of diseases spread byinsects and aided by unsanitary conditions. Many of the flooded areas remained so for months,preventing people from picking up their lives. Many have wondered if this tragedy could havebeen avoided. The floodwaters could, for instance, have been diverted to some of the rivers smallertributaries, minimizing the loss of human life and the damage to property. The severity of theflood was only exacerbated by the construction of various dams and levees, which inhibited therivers ability to regulate itself. This situation was exacerbated by the clear cutting the riverbanksand the building of roads and mines, which raised the silt levels of the river leading toabnormally higher water levels: “Zhuang Guotai of the State Environmental Protection AgencyEcological Section told Worker Daily in early August that for every 70,000 hectares of forestthat is lost, a natural reservoir that can store one million cubic meters of water is lost. Zhuangsaid that the peak flow rate of the Yangtze at Yichang this year is below historic highs. Twenty-three years have had higher flow rates. But the destruction of forests resulted in natural waterstorage loss and silting of rivers and lakes and raised the level of the river further. Theencroachment of land-hungry farmers on lakes reduced the capacity of the environment to absorbfloodwaters. Dongting Lake, a major regulator of Yangtze floods, shrunk from 6000 squarekilometers in 1700 to 4350 square kilometers in 1949 and by another third to just 2820 squarekilometers by 1980.”3 The incredible damage that the flood caused was also in large part due to poor resourcemanagement on the part of the Chinese government. “Farmers faced with a declining amount ofarable land- available per capita are increasingly encroaching on lakes and riverbeds. Balancingthe interests of land hungry farmers with the need to protect against flooding is a difficultquestion of land use policy formulation, regional coordination and enforcement.”4 As more andmore ‘land-hungry farmers’ flock to flood-prone areas, the amount of damage the floods causeincreases along with the number of people in harms way.3 http://www.usembassy-china.org.cn/sandt/fldrpt.htm4 -
  44. 44. 6 The strength of the country’s defenses against floods also need to be strengthened:“Chinese river dikes are designed to withstand the largest flood that might be expected to occurover a ten to twenty year period while in Europe, Japan and the United States, a 100 - 200 yearflood standard applies to large rivers and a 50 - 100 year standard might apply to other rivers.The Chinese standard is calculated by comparing the cost of avoiding flood losses versus thatcost of building massive dikes and reservoir areas to control floodwaters. This formula…doesnot adequately reflect losses to the national economy and to the people of the region.”5 Perhaps the flood was in fact due, in some way, to global warming. Scientists predictedthat a severe flooding of the Yangtze river was likely due to “the strongest El Nino on record inSpring 1997 continuing into the Summer of 1998, the most serious snow disaster of the centuryon the Qinghai - Tibet plateau from November 1997 - February 1998,” and the fact that the“rainfall along the Yangtze River from November 1997 to April 1998 was the highest everrecorded” as illustrated by the chart below: Average Precipitation for the Months of April- August in China 180 160 140 120 Millimeters mm 100 Poly. 80 (mm) 60 40 20 0 19 0 19 2 19 4 66 19 8 19 0 19 2 19 4 76 19 8 19 0 19 2 84 19 6 19 8 19 0 19 2 19 4 19 6 20 8 00 02 6 6 6 6 7 7 7 7 8 8 8 8 9 9 9 9 9 19 19 19 19 20 Year This chart shows the average precipitation in millimeters of the months between Apriland August, which are the rainiest months in China.
