Pollution
Main idea: preventing pollution is more
effective and less costly than cleaning
up pollution
2 main types of pollution
1. Point source - comes from a single,
identifiable source
2 main types of pollution
2. Nonpoint source - dispersed, difficult
to identify
2 main types of pollutants
1. Biodegradable - can be broken down
by natural processes
E.g. sewage, paper, green waste
2 main types of pollutants
2. Nondegradable - natural processes
cannot break them down
e.g. toxins like lead, mercury, ars...
Effects of pollutants
1. Degrades life support systems
for humans and other species
2. Damages wildlife, health,
property

desirable because it would halt
economic growth

  1. 1. Pollution, Causes of Environmental Problems, and Principles of Sustainability Ch. 1, part 2 Living in the Environment Miller and Spoolman, 16th ed.
  2. 2. Pollution Main idea: preventing pollution is more effective and less costly than cleaning up pollution
  3. 3. 2 main types of pollution 1. Point source - comes from a single, identifiable source
  4. 4. 2 main types of pollution 2. Nonpoint source - dispersed, difficult to identify

  21. 21. People in poverty suffer the affects of pollution more acutely No sanitation systems for 38% of the world’s population Water for drinking, bathing, cooking contaminated with human waste
  22. 22. Life-Straw - personal filtration system could save millions Poor Man’s Gatorade Palm full of sugar and a pinch of salt We CAN solve these problems - if we WANT to
  23. 23. Affluence hurts the environment, too High levels of consumption Wasteful use of resources Fueled by advertising making us think having more stuff will make us happy It takes 27 trailers of resources per year for each American
  24. 24. On the other hand… Affluence means having the luxury of caring about the environment
  25. 25. What is your environmental worldview In your notebook, set aside a page titled: My environmental worldview - August, 2010 We will revisit it in May

  31. 31. What are the basic beliefs of your environmental worldview? Record your ideas in your notebook.
  32. 32. 4 scientific principles of sustainability Life on earth has survived and adapted to change for millions of years We can study how and learn how to sustain ourselves
  33. 33. Lessons from nature 1. Rely on solar energy 2. Biodiversity sustains life 3. Population control preserves resources 4. Nutrient cycling - no waste in nature
  34. 34. Quick Write: Choose 1 word to describe what we have been studying so far then Write a short paragraph explaining why you chose that word
