Challenge 20 20_presentation

  1. 1. Challenge 20/20 Presentation
  2. 2. General Information <ul><ul><li>Last year: </li></ul></ul><ul><ul><ul><li>biodiversity, alternative energy and water reclamation in post industrial areas  </li></ul></ul></ul><ul><ul><li>This year: </li></ul></ul><ul><ul><ul><li>Changes in biodiversity within Lake Michigan, specifically in terms of invasive species and low water quality </li></ul></ul></ul>
  3. 3. Borna vs. Milwaukee <ul><ul><li>While we found similarities in our cities, we addressed more specific problems within our region </li></ul></ul><ul><ul><ul><li>Borna: Energy Crisis </li></ul></ul></ul><ul><ul><ul><ul><li>Transition from coal-mining town to more efficient forms of energy  </li></ul></ul></ul></ul><ul><ul><ul><li>Milwaukee: Pollution of Lake Michigan/Runoff </li></ul></ul></ul><ul><ul><ul><ul><li>Retention ponds, bio swales, gardens, underground repositories, urban gardens, rain barrels and green streets </li></ul></ul></ul></ul>
  4. 4. GERMANS! <ul><ul><li>Exchange trip this fall, plus future trips </li></ul></ul><ul><ul><li>Simmilarities between our school and those in both Borna and Leipzig, Germany </li></ul></ul><ul><ul><li>Gives us a new perspective on issues that may not nessisarily be controversial in our area.  </li></ul></ul><ul><ul><li>Chance to exchange information with teens our age in a different part of the world </li></ul></ul>
  5. 5. Effects on Native Species     <ul><li>-Invading species often compete with native ones for the same resources </li></ul><ul><li>-Can lead to ousting of native species </li></ul><ul><li>-Native and invading species can share a niche </li></ul><ul><li>-fundamental to realized niche </li></ul><ul><li>-i.e. barnacles </li></ul>
  6. 6. Asian Carp History <ul><li>carp is up to 95% of the biomass </li></ul><ul><li>History of Carp:bighead, silver, grass and black carp (from Asia) </li></ul><ul><ul><li>bighead carp abundance increase exponentially (population doubles every year) </li></ul></ul><ul><li>How did it get to the Great Lakes?? </li></ul>
  7. 7. Asian Carp's Effects on Other Fauna <ul><ul><li>Harmful to many types of animals because of the Asian carps consumption of low level food chain organisms such as plankton </li></ul></ul><ul><ul><ul><li>Birds </li></ul></ul></ul><ul><ul><ul><li>Insects </li></ul></ul></ul><ul><ul><ul><li>turtles </li></ul></ul></ul><ul><ul><ul><li>etc. </li></ul></ul></ul><ul><ul><li>Consumption  of macrophytes and  macroinvertebrates </li></ul></ul><ul><li>  </li></ul>
  8. 8. Asian Carp Risks <ul><li>Ecological Risks: </li></ul><ul><ul><li>rapid range expansion and population increase--->decrease of native mussels and other invertebrates </li></ul></ul><ul><ul><li>grass carps can eliminate vast areas of aquatic plants which is used for fish food and homes---> reduce recruitment and abundance of native fish </li></ul></ul><ul><ul><li>black carp reduce abundance of mussels and snails </li></ul></ul><ul><ul><li>silver carp tend to jump out at people and hurt them severely </li></ul></ul><ul><li>  </li></ul><ul><li>Threats to Great Lake:  </li></ul><ul><li>some people believe that if invasive species of carp enter the Great lakes, the multi-billion dollar recreational fishing and tourism industry will be devastated     </li></ul><ul><li>1. if they colonize in the GL, decline of native fish---> hurt Great Lake communities that depend on fisheries for its economy (fisheries are valued at 4.5 billion dollars annually) </li></ul><ul><li>2. waterfowl production areas are at risk too (hunters spend more than 2.6 billion dollars on their sport in Great Lakes)---> decrease economic value to communities that benefit from hunting </li></ul>
  9. 9. Asian Carp Video
  10. 10. Response Efforts <ul><ul><li>Increased eDNA (Environmental DNA) monitoring   </li></ul></ul><ul><ul><li>An electrical barrier system  </li></ul></ul><ul><ul><ul><li>Due to safety concerns and monetary problems, this barrier is still largely disputed and not operating at full capacity. </li></ul></ul></ul><ul><ul><li>Chemical controls  </li></ul></ul><ul><ul><li>  Fish harvesting  </li></ul></ul>
  11. 11. Effects of biodiversity loss on humans <ul><ul><li>Vulnerability to natural disasters, global warming </li></ul></ul><ul><ul><li>Already limited, but large amount of species </li></ul></ul><ul><ul><li>Rely on freshwater </li></ul></ul><ul><ul><li>  Ecosystem Services: </li></ul></ul><ul><ul><ul><li>protection of water resources, pollution, stability, maintenance of ecosystems, recovery </li></ul></ul></ul><ul><ul><li>Biological resources: </li></ul></ul><ul><ul><ul><li>food, medicine, breeding stocks, future resources, diversity </li></ul></ul></ul><ul><ul><li>Social benefits </li></ul></ul><ul><ul><ul><li>Research and education, recreation and tourism, cultural values </li></ul></ul></ul>
  12. 12. The Human Element: Why Care? Ethics: T he profit at any cost model used for generations has done irreversable damage to our ecosystems, it is a question of whether or not it is necissary or wise to take of our ecosystems and the species they harbor.  Economics: - The initial impact and damaged caused by invasive species, such as zebra mussel or asian carp, can be a great detriment to all aspects of commerce and impair infrastructure.  Quality of Life: Simply put, if invasive species continue to infiltrate and impact our ecosystems, the quality of nature and living in the surrounding areas will decrease. 
  13. 13. Why 20/20? <ul><ul><li>Forms bonds with students from across the globe </li></ul></ul><ul><ul><li>Gives students from all grades the opportunity to research a problem they see in their world and attempt to find a solution </li></ul></ul><ul><ul><li>You have a long time to complete the project (due in late January at the earliest, May at the latest) </li></ul></ul><ul><ul><li>Some past projects have really made a difference </li></ul></ul><ul><ul><li>FUN!  </li></ul></ul><ul><ul><li>If interested in getting more information about the program, talk to Dr. Wend, Ms. Griffin, Mrs. Konkol or Ali Robinson </li></ul></ul>
