  5. How do humans impact biodiversity? • Introduction of exotic species • Habitat destruction • Hunting/fishing • Pollution • Climate change Other (2%) Known Causes of Animal Extinctions Since 1600 Modified from: http://www.globalchange.umich.edu/globalchange2/current/lectures/biodiversity/biodiversity.html

  7. Habitat Destruction • Ex: Deforestation • Why? • Agriculture • Logging • Mining • Urban sprawl • Why not? • Loss of biodiversity • Increased vulnerability to natural disasters • Loss of ecosystem services Kristin McCully Jami Dywer (Wikimedia) NOAA JoãoCarvalho (Wikimedia)

  10. REVIEW FOOD WEB ACTIVITY The pesticide DDT was used to kill mosquitoes for many years. DDT entered bodies of water, moved up the food chain, and built up in the tissues of fish. When female bald eagles ate these fish, they produced eggs with very thin shells. The eggs broke when the eagles sat on their nests. The U.S. government banned the use of DDT in 1972. Which of these graphs most likely shows how the ban of DDT affected the bald eagle population? D B C A
