Biological Magnification Increase or concentration of a substance, such as the pesticide DDT, in a food chain.
OZONE DEPLETION CFC’s are commonly used as: Refrigerants Styrofoams Solvents Aerosols
OZONE DEPLETION Ozone protects the earth from harmful UVB rays. It has been thinning over Antarctica.
OZONE O 3 UV rays split Oxygen that add to O 2 to make O 3
OZONE DEPLETION Ozone = 0 3 CFC = CCl 4 Cl breaks off an oxygen from ozone

Should the School Use Styrofoam Lunch Trays?
Ozone Depletion Kills Krill (baleen whale food source) Krill is a zooplankton
Krill are dramatically affected by UVB rays. Reports show an 80% drop in the Population of zooplanction off the coast of southern California.

DEFORESTATION Loss of Forests REPLANT
“Slash and Burn”
Erosion is More Likely with Deforestation
pH of Acid Rain The pH of "normal" rain has traditionally been given a value of 5.6. However scientists now believe that the pH of rain may vary from 5.6 to a low of 4.5 with the average value of 5.0.
EXTINCTION End of a species
INVASIVE SPECIES Non-native (or alien) to the ecosystem Kudzu from Japan to stop erosion Garden purple loosestrife is taking over wetlands
Environmental Issues Causes and Effects. Greenhouse Effect Cause: Water vapor, Carbon Dioxide (CO2), methane, and other gases trap heat that radiates.
Learning Targets 20. Explain how habitat destruction, invasive species, and overexploitation lead to a loss of species. 21. Describe how human population.
Human Impact. Invasive Species Non-Native Species enter an ecosystem Invasive Species, Alien Species, Non- Native Species are all the same. Globalization.
Unit 4 Human Impact on the Environment. Population Three factors that affect population: –Number of births –Number of deaths –Number of individuals that.
