  1. 1. Environment By Adrian Licea Lorena Chavez Alejandro Nunez Khasandra Ayon
  2. 2. Why should we care? ~A lot of our environment’s resources have been used up over the years ~We are dealing with more environmental issues every day Climate Change Habitat Loss Water Shortage
  3. 3. Deforestation In nine years, deforestation in the Amazon forest rose from 415,000 to 587,000 km
  4. 4. Why did this occur? ● Mainly seen as a resource for cattle pastures, wood, and housing availability ● Employs at an international level, being a source of agricultural needs ● The demand for food and the need to feed the animals being sustained increases the deforestation rates
  5. 5. Agriculture ● Approximately 80 percent of deforestation in the world is attributed to agriculture. ● Since 1970, 232,000 square miles of Amazon forest have been cleared for agriculture. ● Amazon forest is being cleared at 1.5 acres per second.
  6. 6. Brazil as a Producer of Beef ● Cattle breeding is typically seen in Brazil because it yields huge profits as meat prices are constantly rising. ● Currency devaluation- the devaluation of the Brazilian real against the dollar o Doubled the price of beef in reals o Created an incentive for ranchers to expand pasture areas.
  7. 7. ● According to FAO, the Food and Agriculture Organization of the United Nations, one in each five pounds of commercialized cattle meat is from Brazil. ● Brazil is the second biggest exporter of cattle beef in the world. According to the Foreign Trade Secretariat, Russia (26%), Egypt (17%), Iran (14%), Hong Kong (9%), Chile (6%), Venezuela (5%) and Saudi Arabia (3%) represented 80% of Brazilian cattle beef exports. ● Dairy products import accounted for 50 times the volume exported in 2012. o Brazil is a major importer of dairy products in order to supply the domestic demand. ● Brazilian products are bought mainly by Argentina and Uruguay.
  8. 8. The future...
  9. 9. GLOBAL WARMING ● Global warming refers to an unequivocal and continuing rise in the average temperature of Earth's climate system. ● Since 1971, 90% of the warming has occurred in the oceans. ● "Global warming" is also used to refer to increases in average temperature of the air and sea at Earth's surface. ● Since the early 20th century, the global air and sea surface temperature has increased about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980. ● Each of the last three decades has been successively warmer at the Earth's surface than any preceding decade since 1850
  10. 10. ● Climate change o Rainforests are attributed with being the the world's largest emitters of oxygen ● Endangered Species ○ Loss of habitats will result in endangered species as the forest is home to half the species of plants and animals
  11. 11. Climate Change ● About 20 percent of the worlds oxygen is produced by the Amazon rainforest ● Forests are stripped faster than they can be replanted, therefore, photosynthesis is greatly reduced. o Vegetation continuously recycles carbon dioxide into oxygen
  12. 12. WASTE-DIFFERENT TYPES ● Waste — Electronic waste ● • Great Pacific Garbage Patch ● • Incineration ● • Litter ● • Waste disposal incidents ● • Marine debris ● • Medical waste ● • Landfill ● • Leachate ● • Toxic waste ● •Environmental impact of the coal industry ● • Exporting of hazardous waste
  13. 13. ~ Pacific Garbage Patch is a collection of debris in the Northern Pacific Ocean ~This gyre lies in between Hawaii and California ~ The motion of the gyre prevents debris from escaping ~ Micro Plastics make up the majority of garbage patches
  14. 14. ~ Plastic isn’t biodegradable, instead it breaks down into tiny pieces known as micro plastics ~ Marine debris is very deadly to a lot of sea creatures Sea turtles often mistake plastic bags for jellyfish which are their favorite food
  15. 15. POLLUTION-DIFFERENT TYPES ● Pollution — Nonpoint source pollution • Point source pollution • Light pollution • Noise pollution • Visual pollution • Interplanetary contamination Water pollution — Acid rain • Environmental impact of the coal industry • Eutrophication• Groundwater recharge • Marine pollution • Ocean dumping • Oil spills • Thermal pollution • Urban runoff • Water crisis • Marine debris • Microplastics • Ocean acidification • Ship pollution • Wastewater • Fish kill • Algal bloom • Mercury in fish •Environmental impact of hydraulic fracturing Air pollution — Atmospheric particulate matter•Environmental impact of the coal industry • Smog • Tropospheric ozone • Indoor air quality • Volatile organic compound •Environmental impact of hydraulic fracturing
  16. 16. Iraq War Effects of Depleted Uranium ~ Left behind in inhabited areas ~ Birth Defects, Cancer ~ Tainted water/food supplies
  17. 17. ● 10 million barrels of oil spilled ● Water supply still contaminated today ● Destroyed aquatic ecosystems ● Temperature dropped 10 degrees due to absence of sunlight
  18. 18. Chernobyl 1986 Cold war Disaster -Largest uncontrolled radioactive realease - Rapid increase in Thyroid Cancer - Fetal Deaths - Attributed to faulty reactor design and inadequate staf according to the WNA.
  19. 19. Agent Orange 80million Liters Dropped -Polluted water supplies -Birth Defects -Continues effects today -5million acres affected -Inhabitants heavily afflicted
  20. 20. Napalm ● Used in Vietnam and Tokyo ● Death by burn or asphixiation. ● Destroys Vegetation
  21. 21. Keystone XL Pipeline
  22. 22. What is the Keystone XL Pipeline? Keystone XL Pipeline is an oil pipeline that runs through the US and Canada. More specifically it runs from Alberta, Canada to refineries in Nebraska, Illinois, and Texas and also carries light crude oil from Montana to N. Dakota. ● The pipeline is highly controversial as it faces criticism from environmentalists and congress because of the pipeline's impact on Nebraska's Sand Hills region.
  23. 23. Criticisms of Keystone XL Pipeline -risk of spills alone pipeline path and could potentially mess up a highly sensitive region of Nebraska’s Sand Hills -12-17% higher greenhouse gas emissions from the extraction of oil sands -Also pipeline spills would pollute air, water, supplies, and harm birds & wildlife -Ogallala Aquifer, one of the largest reserves of fresh water in the world provides drinking water for 2 million people and supports $20 billion in agriculture. A leak would ruin drinking water and also devestate Midwestern US economy.
  24. 24. California Drought ● California is facing one of the driest years ever recorded since rainfall has been recorded in 1849. ● Obama has recognized the drought in California as a problem. Possible reasons for the drought? ● Man-made climate increases make California hotter today than it has been in the past.
  25. 25. The drought is already affecting snow covered areas, greatly decreasing the total amount of snowfall and snow that covers the floor in places like Lake Tahoe. Places like Yosemite National Park are actually offering horseback riding and hikes to those who visit (when normally at this time of year, Yosemite attracts skiers).
  26. 26. Who cares? ● Lack of water may cause an increase in the prices of food ● Increased forest fires ● Conflict over available water ● Possible water rations, or increased water cost
  27. 27. Solutions to Environmental Problems ● Creating a clean energy future Our demand for oil in our oil dependent economy threatens the environment and other countries have already been making progress in being green.
  28. 28. Cleaner, better cars ● Electric cars provide a affordable monthly price for transportation.
  29. 29. ENERGY USE-ENVIRONMENTAL ISSUES ● Energy — Energy conservation • Efficient energy use • Environmental impact of the coal industry • Environmental impact of the energy industry • Environmental impact of hydraulic fracturing • Renewable energy • Renewable energy commercialization •
  30. 30. Elio, Ultra High Mileage Vehicle ● Newer better cars reduce the amount of gas we consume, saving you money at the pump and reducing our dependency on oil. ● 84 Miles per gallon ● Only $6,800 new ● Made in the USA
  31. 31. Hemp ● Hemp vs. Marijuana ● Hemp is the variety of the cannabis plant that secretes low-grade THC in negligible amounts of less than 0.3%. ● Marijuana is rich in THC, with content ranging from 2 to 20% ● THC, short for tetrahydrocannabinol, is a chemical compound found in the cannabis plant. o In low doses, the compound causes some pain reduction, may reduce aggression, can stimulate appetite, and may help reduce nausea. o Higher doses may cause the “high” associated with marijuana, leading to altered perception of time and space, and fatigue.
  32. 32. Environmental Benefits of Hemp ● Fuel o One acre of hemp yields 1,000 gallons or 3,785 liters of fuel. ● Compared to Cotton ○ 1 acre of hemp will produce as much as 2-3 acres of cotton ○ Hemp replaces cotton as a raw material in the manufacturing of paper and cloth ● Paper ○ One acre of hemp (grown in a single season) yields as much paper as up to 4 acres of trees.
  33. 33. Hemp ● Low Maintenance o The high amount of pesticides and herbicides used on cotton amount to 50% of the world’s usage, as against none in the case of hemp. ● Switching to hemp paper could reduce deforestation significantly. For every 4 acres of trees that are required annually to make paper, only an acre of hemp would be required. ○ Hemp paper can be recycled up to 7 or 8 times), much less is needed. ○ In comparison, paper from wood pulp can only be recycled around 3 times
  34. 34. ● Hemp can actually clean up toxins from the ground. o This process is called phyto-remediation. o A good example of this is when hemp was used to help clean up the Chernobyl nuclear disaster site to remove radioactive elements from the ground. o Phyto-remediation can be used to remove nuclear elements, and to clean up metals, pesticides, solvents, crude oil, and other toxins from landfills. Hemp breaks down pollutants and stabilizes metal contaminants by acting as a filter.
