6 Bubble thinking map! Use adjectives /adverbs phrases to describe Developed countries or Pollution at least 5 descriptions.

7 The Tragedy of the Commons 1968-Garret Hardin came up with the idea of the tragedy of the commons. In his example, the commons is the area that the whole village uses. Therefore, anyone can use it.

8 Tragedy of the Commons The old definition: The commons were an area that people would put sheep or cows on. The commons belonged to everyone. According to this idea, it is better in the short-term interest of the individual to use as much of this resource as possible. The thought is, if I don t use this space, someone else will!! In the long term, who suffers? EVERYONE! Why?--if too many animals grazed on the grass, the grass would all die. Everyone suffered because no one could use the grass

9 Tragedy of the Commons Overgrazed Land

11 The Earth s Natural Resources are our modern commons Modern Commons Examples: Air, water, wildlife What are we doing??

12 Modern Commons If no one takes responsibility for the Earth s Natural Resources, what will happen to them according to the Tragedy of the commons? Our resources will become overused and depleted.

13 It s Not All Bad What Hardin didn t account for was the social nature of humans--we need each other for survival. We can solve these problems by planning, organizing, considering scientific evidence and proposing a solution. Personal sacrifices will have to be made

14 If a farmer overgrazes his sheep in a common pasture, the end result is more harm than benefit. This example illustrates. a. The Law of supply and demand b. The Tragedy of the Commons c. Statistical Crisis d. Coevolution

15 NAME THREE PERSONAL SACRIFICES THAT YOU ARE WILLING TO MAKE TO PROTECT OUR EARTH.

16 Start up Define vocab. Section 1.2 page 16 Obj: Law of supply and demand Ecological footprint Sustainability turn in your start ups from Fri Turn in your ecological footprint paper.

17 Economics and The Environment 1) The Law of Supply and Demand: -States that the greater the demand for a limited supply of something, the more that thing is worth.

18 Gasoline adheres to the laws of supply and demand Economics and the Environment

19 The cost of gasoline remains high, because it is a limited natural resource and the demand is high

20 2) Cost-Benefit Analysis A cost-benefit analysis balances the cost of the action versus the benefits one expects from it. Results often depend on who is doing the analysis An industry may believe the cost of reducing pollution may outweigh the benefits, but to a nearby neighbor, the benefits may be worth the price. The cost of environmental regulations is passed onto the consumer

21 Cost benefit examples cleaning up air or water pollution Cleaning up a polluted river Correction of sewage overflow sites Eliminating air pollution from smoke stakes Electric cars Trash recycling

22 Developed and Developing Nations The Seven Indicators that determine the development statue of a country 1. Health 2. Population Growth 3. Wealth 4. Living Space 5. Energy Use 6. Pollution produced 7. How Waste is handled

23 Developed Nations Have Higher average incomes Slower population growth Diverse industrial economies Stronger social support systems

24 Examples of Developed Nations France

25 Examples of Developed Nations Canada

26 Examples of Developed Nations The good old USA

27

28 Developing Nations Some Characteristics: Lower average incomes Simple and agricultural based economies Rapid population growth

29

30 Examples of Developing Nations Mexico

31 Examples of Developing Nations Malaysia

32 Examples of Developing Nations Brazil

33 Forests are stripped Bare Severe Overpopulation And the environmental problems that come with it Topsoil is depleted Logging site in Canada Animals become extinct Dust Bowl Bachman s Warbler

34 Severe Overpopulation And the personal health problems that come with it Malnutrition Disease Starvation Scurvy-lack of vitamin C Plague-bacterium that is vectored through a flea. Killed lots of people during the middle ages

35 Developed Nations use a lot of Resources Developed nations use up 75% of the world s resources even though they only make up 20% of its population. The American Dream Never Forget How Lucky You Are

36 World map by quartiles of Human Development Index in Very High High Medium Low Data unavailable

37 Start up Which of the following will NOT reduce your ecological footprint? a. leaving electronics on or plugged up when they are not in use b. carpooling or biking when possible c. drinking tap water out of a reusable cup instead of water in disposable plastic bottles d. taking shorter showers

38 A person s ecological footprint: -shows the productive area of Earth needed to support one person in a particular country. -it estimates the land use for crops, animals, forest products, and housing -also includes ocean area for fish and forest area needed to absorb pollution from fossil fuels Ecological Footprint

39 An acre is ~75% the size of a football field. Or 209 feet X 209 feet Developed acres Developing 4.4 acres

40 Environmental Problems are very complex. In recent years, the environment has become a battleground for larger issues that affect humanity Environmental Science in Context

41 Environmental Issues are often distorted, oversimplified, or sensationalized by the media. What is one thing you can do to make informed decisions even when hearing biased info.? Listen to many viewpoints; people have opinions and reasons why they feel the way they do Try to understand those reasons before reacting Critical Thinking

42 Sustainability Definition: -the condition in which humans and nature can exist in productive harmony. Human needs (water, power, food, housing) are met indefinitely.

43 What about this??? And this??
