1. CHAPTER 1 SECTION 2 THE ENVIRONMENT AND SOCIETY

2. LEARNING TARGETS Students will understand the big idea behind “The Tragedy of the Commons.” Students will have an understanding of the law of supply and demand. Students will know the differences between developed countries and developing countries. Students will have an understanding of “SUSTAINABILITY.”

3. SOCIETY AND THE ENVIRONMENT How does society use common resources? How do we decide to share common resources?

4. “THE TRAGEDY OF THE COMMONS” This is what your fish activity was based off of, and was written in an essay by ecologist Garret Hardin! The main difficulty in solving problems is the conflict between short-term interests of individuals and long- term welfare of society Hardin used commons (shared pieces of land) to illustrate how humans often consider personal interest over society’s welfare. The point someone must take responsibility for maintaining resources so they are not depleted. Our natural resources are our modern commons.

5. ECONOMICS AND ENVIRONMENT Supply and Demand Costs and Benefits Risk Assessment Developed vs. Developing Countries Populations and Consumption

6. SUPPLY AND DEMAND The law of supply and demand- The greater the demand for a limited supply of something, the more that thing is worth Consider Oil- If supply decreases, we have three choices: Pay more, use less, find new energy source

7. COSTS & BENEFITS The costs of solutions can be high Cost- Benefit Analysis Balances costs of action against the benefits one expects from it It is often cheaper to produce a product with less environmental safeguards

8. RISK ASSESSMENT A tool that helps us create cost- effective ways to protect our health and the environment To come up with effective solutions the public must perceive the risk accurately, which doesn’t always happen

9. COUNTRIES CONSUMPTION Developed Have higher average incomes, slower population growths, diverse economies, strong social support systems Developing Lower average incomes, simple agricultural based economies, rapid population growth

10. SUSTAINABILITY The condition in which human needs are met in such a way that a human population can survive indefinitely

11. SUSTAINABILITY Currently does NOT exist Standards of living are too high The problem is not insurmountable Requires everyone’s participation “We must find solutions that allow people on all parts of our planet to live in a clean, healthy environment and have the resources they need for a good life”

12. CONSUMPTION Ecological footprint- the productive area of Earth needed to support one person in a particular country Guess what citizens of Earth have the highest ecological footprint.
