1. According to this story, King Shihram was a tyrant who oppressed his subjects. One of his subjects, a wise man named Sissa ibn Dahir, invented the game of chess for the king to play, to show him that a king needed all his subjects and should take good care of them. King Shihram was so pleased that he ordered that the game of chess should be preserved in the temples, and said that it was the best thing he knew of to train generals in the art of war, a glory to religion and the world, and the foundation of all justice.tyrant religion Then King Shihram asked Sissa ben Dahir what reward he wanted. Sissa answered that he didn't want any reward, but the king insisted. Finally Sissa said that he would take this reward: the king should put one grain of wheat on the first square of a chessboard, two grains of wheat on the second square, four grains on the third square, eight grains on the fourth square, and so on, doubling the number of grains of wheat with each square (an exponential rate of growth).wheat A Story...

2. "What a dummy!" thought the king. "That's a tiny reward; I would have given him much more." He ordered his slaves to bring out the chessboard and they started putting on the wheat. Everything went well for a while, but the king was surprised to see that by the time they got halfway through the chessboard the 32nd square required more than four billion grains of wheat, or about 100,000 kilos of wheat. Now Sissa didn't seem so stupid anymore. Even so, King Shihram was willing to pay up.slaves But as the slaves began on the second half of the chessboard, King Shihram gradually realized that he couldn't pay that much wheat - in fact, to finish the chessboard you would need as much wheat as six times the weight of all the living things on Earth.

3. Exponential Growth Defn: quantity increases by a fixed percentage per unit of time – it’s deceptive!!!

A Brief Historical Perspective Environmental Science: Discovery of carbon dioxide accumulation in the atmosphere, 1957 - Roger Revelle and Charles Keeling Publication of Silent Spring by Rachel Carson, Sept. 27, 1962 – Discovery of atmospheric ozone depleting chemicals, 1974 -- F. Sherwood Rowland and Mario J. Molina

10. Sustainability The Central Theme Natural capital: supported by solar capital – Natural resources – Natural services E.g., nutrient cycling Degradation of natural capital through human activities Scientific solutions Trade-offs/compromise

12. Environmentally Sustainable Societies Protect Natural Capital and Live off Its Income Live off natural income (HW exercise) Human activity and its affect on the earth’s natural capital

13. Think of natural capital as money. You inherit $1,000,000 (natural capital). You earn 10% annual interest at the bank ~ $100,000 your income. However... You use $200,000 each year. How long before you run out of natural capital? 1,000,000 +100,000 = 1,100,000 - 200,000 900,000 + 90,000 = 990,000 - 200,000 790,000 + 79,000 = 869,000 - 200,000 669,000 + 66,900 = 735,000 - 200,000 535,000 + 53,500 = 588,000 - 200,000 388,000 + 38,000 = 426,800 - 200,000 226,800 + 22,680 = 249,480 - 200,000 49,480 + 4,948 = 54,428

15. Renewable Resources Sustainable yield Environmental Degradation Terms: (add to notes)

17. Overexploiting Shared Renewable Resources: Tragedy of the Commons Three types of property or resource rights – Private property – Common property – Open access renewable resources Tragedy of the commons – Solutions

18. Tragedy of the Commons Therein is the tragedy. Each man is locked into a system that compels him to increase his [input] without limit – in a world that is limited. Ruin is the destination toward which all men rush, each pursuing his own best interest in a society that believes in the freedom of the commons (Hardin, 1968, p. 1244).

19. Terms Nonrenewable resources Reuse Recycle

20. Consumption of Natural Resources

21. Our Ecological Footprints Are Growing Ecological footprint concept – Biological capacity – Ecological footprint

23. For everyone to live as Americans?

24. Case Study: China’s New Affluent Consumers Two-thirds of the most polluted cities are in China Projections, by 2020 – Largest consumer and producer of cars – World’s leading economy in terms of GDP PPP Leading consumer of various foods and goods Wheat, rice, and meat Coal, fertilizers, steel, and cement Second largest consumer of oil

25. Pollution Comes from a Number of Sources Sources of pollution – Point E.g., smokestack – Nonpoint E.g., pesticides blown into the air Main type of pollutants – Biodegradable – Nondegradable Unwanted effects of pollution

26. Experts Have Identified Five Basic Causes of Environmental Problems Population growth Wasteful and unsustainable resource use Poverty Failure to include the harmful environmental costs of goods and services in their market prices Insufficient knowledge of how nature works

28. Poverty Has Harmful Environmental and Health Effects Population growth affected Malnutrition Premature death Limited access to adequate sanitation facilities and clean water

29. Prices Do Not Include the Value of Natural Capital Companies do not pay the environmental cost of resource use Goods and services do not include the harmful environmental costs Companies receive tax breaks and subsidies Economy may be stimulated but there may be a degradation of natural capital

30. We Can Learn to Make Informed Environmental Decisions Scientific research Identify problem and multiple solutions Consider human values

31. Steps Involved in Making an Environmental Decision

33. Nature has sustained itself for billions of years by using solar energy, biodiversity, population control, and nutrient cycling— lessons from nature that we can apply to our lifestyles and economies.
