12. Comprehension Check
Using what you know about supply and demand , explain why oil prices effect the price of say, groceries?
Explain how you have used a cost / benefit analysis in your life.
How do risk assessments factor into environmental law making?

14. 1st World (Developed) Countries
Higher avg. income
Diverse industrial economies
Slower population growth
Strong support systems
- social security
- welfare
- food stamps
- education

15. EXAMPLES 1st world
First World: United States, United Kingdom and their allies.

"Third World" term is also often taken to include newly industrialized countries like Brazil, China and India.

18. ARE there 2nd and 4th worlds categorizations?
If so – please use your powers of deduction / inference to determine the characteristics of each.

27. LOOK UP STATISTICS: for developed and non-developed nations: list website(s) used

Population growth
Then do questions on the study guide that pertain to this lesson.

31. QUIZ TOMORROW

32. Population and Consumption
Local Pressures – When population in an area grows rapidly, there may not be enough resources for everyone to live comfortably.
Forests are stripped bare
Topsoil is exhausted
Animals are driven to extinction
Malnutrition, Disease and Starvation are constant threats.

33. As population grows – what happens to people?
More people = fewer resources for each person
Of the 4.5 billion people in developing countries fewer than HALF have…
Access to CLEAN water
Enough FOOD
Proper SANITATION

34. Consumption Trends Developed nations are the most wasteful
Developed nations account for 20% of the world population BUT use 75% of the worlds resources.
Affluence = Pollution
Let’s look at the chart on page 19

35. Ecological footprint
An ecological footprint shows the productive area of Earth needed to support one person in a particular country.
Estimated land use for forest use, crops, grazing and housing.
Also includes ocean area used to produce seafood and forest area needed to absorb pollution caused by fossil fuel use.
What is your ecological footprint compared to other nations?

36. Hmmm…..
Why do people in developing countries have a smaller ecological footprint than those whom live in developed countries?

37. Sustainability Key goal of environmental success is SUSTAINABILITY.
Sustainability is when human needs are met in a way that the Earth can support life indefinitely.

38. Watch Footprint video and comment.
