  2. 1-1 LIVING SUSTAINABLY

  3. Questions to ask • How the Earth works? • How are we affecting the Earth’s life supports system? • How to deal with environmental problems? • What laws? When do we phase it in?

  4. What do you think is our most serious environmental problem? • Corruption in governments and businesses, and bad economic policies • Destruction of biodiversity • Environmental impacts from human poverty and hunger • Genetic engineering of organisms • Greenhouse Effect (global warming) and resulting climatic changes • Human diseases (cancer, malaria, AIDS, etc.) • Human overpopulation • Nuclear, chemical and biological weapons of mass destruction • Poor farming techniques (soil erosion, overuse of pesticides, livestock wastes, etc.) • Wasting of valuable and nonrenewable resources

  5. Six important environmental issues • Population growth • Increasing resource use • Global climate change • Premature extinction of plants and animals • Pollution • Poverty

  6. LIVING SUSTAINABLY • SOLAR CAPITAL - PROVIDES 99%OF OUR ENERGY WE USE ON EARTH. • EARTH CAPITAL - LIFE-SUPPORT AND ECONOMIC SERVICES. • SUSTAINABILITY - IS THE ABILITY OF A SPECIFIED SYSTEM TO SURVIVE AND FUNCTION OVER A SPECIFIED TIME.

  7. SUSTAINABLE RESOURCE HARVEST • SUPPLY OF RESOURCES THAT CAN BE HARVESTED EACH YEAR.

  8. SUSTAINABLE EARTH • EARTH CAPITAL ARE USED AND MAINTAINED OVER TIME.

  9. What is sustainability? • Satisfying basic needs without depleting or degrading resources • Maximizing resource use • Reducing resource use even if it means some big sacrifices by human beings • Halting further resource use and limiting human progress

  10. SUSTAINABLE SOCIETY • MANAGES ITS ECONOMY AND POPULATION SIZE WITHOUT EXCEEDING ALL OR PART OF THE PLANET’S ABILITY TO ABSORB ENVIRONMENTAL INSULTS, REPLENISH ITS RESOURCES, AND SUSTAIN HUMAN AND OTHER FORMS OF LIFE OVER A SPECIFIED PERIOD. HUNDREDS OF YEARS.

  11. CARRYING CAPACITY • DEFINED AS THE MAXIMUM NUMBER OF ORGANISMS A LOCAL,REGIONAL,OR GLOBAL ENVIRONMENT CAN SUPPORT OVER A SPECIFIED PERIOD.

  12. CARRYING CAPACITY • VARIES BY LOCATION • GLOBAL CHANGES • TYPES OF TECHNOLOGY USES TO EXTRACT AND PROCESS THE RESOURCES

  13. ARE WE LIVING OFF THE INTEREST OR THE PRINCIPAL?

  14. 1-2GROWTH AND THE WEALTH GAP

  15. LINEAR POPULATION GROWTH • IS A QUANTITY THAT INCREASES AT A CONSTANT AMOUNT PER UNIT OF TIME. • IF PLOTTED ON A GRAPH IT WOULD BE A STRAIGHT LINE.

  16. EXPONENTIAL GROWTH • IS WHERE THE QUANTITY INCREASESBY A FIXED PERCENTAGE OF THE WHOLE IN A GIVEN TIME AS EACH INCREASE IS APPLIED TO THE BASE FOR FURTHER GROWTH. • IS J SHAPED. • DOUBLING TIME - THE RULE OF 70. • 70/% OF GROWTH RATE = DOUBLING TIME IN YEARS. • k = (1/t)ln(N/N0) • t = (1/k)ln(N/N0)

  18. The earth’s population is currently 6.6 billion people. The rate of population growth is 1.2 percent. How large will the earth’s population be after 58 years? • 10.2 billion people • 12.6 billion people • 13.2 billion people

  19. Which of the following would not be an example of sound science? • Calculating the destruction of trees in a forest based on historical cut rates • Calculating the pollution in a stream based on chemical analysis • Developing a plan on how to conserve resources based on opinion polls • Forecasting CO2 levels in a region based on historical emissions

  20. Because developing nations make up 81% of the world’s population, they generate most of the pollution and waste as well as using most of the world’s resources. • True • False

  21. Based on the map, in which three countries would you not expect to find high levels of poverty? • United States, Argentina, Japan • United States, China, Australia • Greenland, Kenya, South Africa • Mexico, Brazil, Canada

  22. How many people live on the earth? • About 5 million • About 2 billion • Over 6 billion • Over 10 billion

  23. 6739359653

  24. DEVELOPING COUNTRIES • LOW INDUSTRIALIZATION AND PER CAPITA GNPs. • MAKES UP 80% OF THE WORLDS POPULATION. • 15% OF THE WORLD’S WEALTH AND INCOME. • ONLY USE 12% OF THE WORLD’S RESOURCES.

  25. Most population growth is projected to occur in: • Developed countries • Developing countries

  26. More Developed Country Less Developed Country

  27. WHAT CAN BE DONE ABOUT THE WEALTH GAP? • NOTHING, BECAUSE PEOPLE MAKE THEIR OWN BED SO THE MUST LIVE IN IT. IF WE HELP THEM WE WILL BE CREATING A WELFARE STATE.THUS HURTING THEM IN THE LONG RUN. • SOMETHING, BECAUSE THE POOR ARE DYING. THE POOR SOMETIMES HAVE A MORE ADVERSE AFFECT ON THE ENVIRONMENT THAN THE DEVELOPED COUNTRIES.

  28. TOO MANY RICH PEOPLEWEIGHING RELATIVE BURDENS ON THE PLANET • READ PAUL EHRLICH’S ESSAY. • WRITE A COUNTER POINT ESSAY. • TYPED 2 pages. • 20 POINTS. Test points • Due Friday the 9th

  29. 1-3RESOURCES

  30. Nonrenewable resources: • Are fixed in quantity • Include solar energy • Degrade quickly once they have been extracted from the earth • Can be exhausted completely

  31. WHAT IS SUSTAINABLE DEVELOPMENT? • IS THE CURRENT GROWTH RATE SUSTAINABLE IN THE FUTURE? • THIS IDEA ASSUMES THAT WE RIGHT TO USE THE EARTH’S RESOURCES AND EARTH CAPITAL TO MEET OUR NEEDS BUT THAT WE HAVE THE OBLIGATION TO PASS ON THE EARTH’S RESOURCES AND SERVICES TO FUTURE GENERATIONS IN AS GOOD OR BETTER SHAPE THAN THESE CONDITIONS WERE PASSED ON TO US. • SHOULD WE LIVE FOR TODAY AND NOT CARE ABOUT HOW FUTURE WILL BE AFFECTED?

  32. ECOLOGICAL VS. ECONOMIC RESOURCES • ECOLOGICAL RESOURCE - IS ANYTHING REQUIRED BY AN ORGANISM FOR NORMAL MAINTENANCE, GROWTH, AND PRODUCTION. • ECONOMIC RESOURCE - IS ANYTHING OBTAINED FROM THE ENVIRONMENT TO MEET HUMAN NEEDS AND WANTS.

  33. RENEWABLE RESOURCES • RENEWABLE RESOURCES - SOLAR. • POTENTIALLY RENEWABLE RESOURCES - CAN BE REPLENISHED FAIRLY RAPIDLY THROUGH NATURAL PROCESSES. • BIODIVERSITY GENETIC DIVERSITY SPECIES DIVERSITY ECOLOGICAL DIVERSITY VARIETY PROVIDES MORE RESOURCES.

  34. Which of the following countries has the highest ecological footprint per capita? • India • The Netherlands • The United States • All are about the same
