1. CHAPTER 1 Environmental Science: A Global Perspective
“All the flowers of all the tomorrows are in the seeds of today.” Chinese Proverb

2. (What do you consider to be our most important environmental problems
(What do you consider to be our most important environmental problems? (How can science help solve these problems

3. Environmental Science
Defined as the study of all living and non living factors in an ecosystem and how human activity impacts the natural cycles.
(industry, government, daily living)

4. Where Does it go?
Environmental Science is called an applied science. Why?
Bio, chem, earth and space etc are pure sciences.

5. History of problems: Industrial might, scientific and technological advances caused major advances without regard to environmental impact.

6. Critical thinking: Is the damage to the environment worth the advances to our lifestyle?? Discuss

7. Environmental Problems are broken down into three main categories. I
Environmental Problems are broken down into three main categories. I. Resource Depletion II. Pollution III. Extinction

8. Resource Depletion: when a large part of the resource has been used up
Resource Depletion: when a large part of the resource has been used up. Any natural substance that can be used by living things could be considered a natural resource. ie/ Air, water, soil, light, minerals, plants, animals.  

9. Renewable and Nonrenewable resources are affected.
What is the difference between the two?.
Renewable resources have an unlimited capacity to generate energy.. ie/ sun, wind, moving water, geothermal
Non renewable resources will not be replenished as they are used up…ie/ fossil fuels, nuclear fuels

10. Extinction: The last individual member a species is dead and gone forever. Problem: Many are gone before identification or study. Why is this a problem?

11. Pollution: when there is a large introduction or harmful levels of chemicals or waste material introduced into the environment. ie/ “cides”, fertilizers, heat (thermal).
* How could heat be harmful to a water ecosystem?
* How could fertilizers harm the environment?

12. Biosphere - the thin layer of life around the Earth that sustains all life. Approx: 5miles below and 5miles above sea level.

14. Developed Country- US Can
Developed Country- US Can. Japan, Australia, New Zeland, and the countries of Western Europe

15. Highly Industrialized and higher income = a higher standard of living
Highly Industrialized and higher income = a higher standard of living. What does standard of living mean?
Standard of living: Medical Care, Food, Shelter, Education, Availability of goods (etc)

16. Generally these countries have greater potential for pollution and consumption problems. (Less % of population but higher rate of resource consumption and pollution.

17. Developing Country - India, Bangladesh, Some Central American countries, Malaysia, Thailand.

18. Describe an underdeveloped country…
No education system
No medical care
Not enough food for most citizens
Inadequate housing
No economic system

19. Make between $0 and $2,700 per year
Make between $0 and $2,700 per year. Several of these countries are making economic advances.

20. What steps could these developing countries take to protect the environment?
Development

21. Developed Countries have approx 1
Developed Countries have approx 1.75 billion: 68% energy consumption rate
Developing Countries have about 6.25 billion: 32% energy consumption rate.

22. Population Crisis- when regions population is growing too quickly for sustainable living.
Do population crisis occur in the wild? Birth Patterns and circadian rhythm

23. Population crisis is most severe in developing countries. WHY
Population crisis is most severe in developing countries. WHY? depletion, extinction, disease, malnutrition etc. are factors.

24. Consumption crisis is most severe in developed countries. WHY?
Consumption Crisis- Use up, waste or pollute faster than can be replaced, renewed or cleaned up.
Consumption crisis is most severe in developed countries. WHY?

25. Sustainable World- a world where human populations can exist indefinitely with a high standard of living and health. (Three “R’s”)

26. Making Environmental Decisions

27. Values that affect environmental decision making:

28. Aesthetic -- beautiful or pleasing   Economic -- gain or loss of $ or jobs   Environmental --protection of natural resources

29. Educational -- accumulation & use of knowledge   Ethical/ Moral -- what is right and wrong   Health -- human health & disease

30. Recreational -- leisure activities   Scientific -- increase understanding of natural world   Social/Cultural -- maintain communities and respecting values & traditions of others.
