1. Chapter 22-25 OMG The Last Presentation

2. The Green House Effect Top Greenhouse Gases? Water Vapor Carbon Dioxide Methane NOx CFC’s Ozone Tropospheric

3. Where does the Greenhouse effect occur? Troposphere Keeps the earth warm Increase in gases can heat the earth too much Since the industrial revolution in the 1800’s CO2 has been on the rise As CO2 increases so does temperature

4. How is CO2 measured?

5. Whats the worst that can happen? Sea level Rises/Destroying Coastal Communities Flooding Drought Loss of Biomes/Habitat Destruction More severe storms

6. The Albedo Effect Albedo is a fancy word for reflective ability Dark colors absorb heat energy thus speeding up global warming Ice/White Reflects most of the heat energy thus keeping the temperature stable and cool Ice has HIGH Albedo Dirt has low Albedo

7. Chapter 23 Extinction and Biodiversity Biodiversity These are characteristics of Biodiverse locations Genetic Diversity Species Diversity Ecosystem Diversity

8. Biodiversity Remember Species Evenness Species Dominance Simpson's diversity index-Counts number of species Shannon Weiner index- a method of calculating biodiversity that includes species evenness and dominance

9. Importance of Biodiversity Interconnectedness Future Resources Aesthetic/Intrinsic Economical/ Tourism

10. Extinction Endangered Species are species at risk of extinction Ex. Dodo Bird, Passenger Pigeon Characteristics that make species vulnerable K-Strategist Specialist Species Obligate Symbionts Ex, Panda

11. Other Reasons Medicinal Purposes Perceived as Pests Commercially Valuable Poaching

12. Commercially Economical

13. Causes for Extinction Number 1 Reason- Habitat Destruction Poaching/Hunting Competition/Invasive Species Classic Examples Cane Toad, Zebra Mussels, Kudzu Plant, English Ivy

14. Invasive Continued Escaped Pets Bermese Python in the Everglades eating Caimen alligator

15. How to Fix Habitat Preservation Captive Breeding Programs Legislation Endangered Species Act (ESA) Convention on International Trade in Endangered Species (CITES)

16. Vocabulary Mass Extinction Background Extinction Anthropogenic Extinction DODO and RAT

17. Chapter 24 Economical and Env. Issues Cost Benefit Analysis Externalities Full Cost Pricing Legislations-Fees for pollution

18. Ex. Short term Vs. Long term Tragedy of the Commons Fracking Clear Cutting Solar Panels

19. Globalization Leads to Exploitation As long as we have different minimum wages workers and resources will continue to be exploited Tragedy of the Commons

20. Chapter 25 Laws NEPA-National Environmental Policy Act Requires companies to file a EIS Environmental Impact Statement EPA- Environmental Protection Agency (Nixon) 1970 Protect human health CWA-Clean Water Act 1972 made in response to Cuyahoga River Fire, protects our waters from point and non-point sources

21. More Acts Safe Drinking Water Act -SDWA 1974 Protects our drinking water The Clean Air Act- 1963 Made laws regarding emissions Established cap and trade

22. More Acts Montreal Protocol-Ban on CFC’s Kyoto Protocol- a movement to limit the amount of Carbon USA-Did not sign CERCLA- Comprehensive Environmental Response, Compensation and Reliability Act AKA: Superfund Cleans up toxic spots, Holds companies liable

23. More Acts Resource Conservation and Recovery Act: RCRA Cradle to the Grave ESA-Endangered Species Act CITES- Bans the international transport of wildlife and fauna
