  2. BIO40A: GENERAL ECOLOGY I. What is Ecology? A. Definitions: ?

  3. BIO40A: GENERAL ECOLOGY I. What is Ecology? A. Definitions: "The scientific study of the distribution and abundance of organisms, and their interactions with the environment."

  4. BIO40A: GENERAL ECOLOGY I. What is Ecology? A. Definitions: B. Why is this important? ?

  5. BIO40A: GENERAL ECOLOGY I. What is Ecology? A. Definitions: B. Why is this important? 1. Pragmatic Reasons

  6. BIO40A: GENERAL ECOLOGY I. What is Ecology? A. Definitions: B. Why is this important? 1. Pragmatic Reasons - Humans are organisms that interact with the environment - we are dependent upon it, and affect it.

  7. Human Ecology: - distribution...

  8. Human Ecology: - distribution...

  9. Human Ecology: - distribution...

  10. Human Ecology: - distribution...

  11. Human Ecology: - distribution...

  12. Human Ecology: - distribution... and abundance...

  13. Human Ecology: - distribution... and abundance... - 1 billion: ...to about 1850

  14. Human Ecology: - distribution... and abundance... - 1 billion: ...to about 1850 - 2 billion: 1928 (about 78 yrs) Five Points - Atlanta

  15. Human Ecology: - distribution... and abundance... - 1 billion: ...to about 1850 - 2 billion: 1928 (about 78 yrs) - 3 billion: 1960 (about 32 yrs)

  16. Human Ecology: - distribution... and abundance... - 1 billion: ...to about 1850 - 2 billion: 1928 (about 78 yrs) - 3 billion: 1960 (about 32 yrs) - 5 billion: 1987 (about 15 yrs/billion)

  17. Human Ecology: - distribution... and abundance... - 1 billion: ...to about 1850 - 2 billion: 1928 (about 78 yrs) - 3 billion: 1960 (about 32 yrs) - 5 billion: 1987 (about 15 yrs/billion) - currently 6.5 billion

  18. Human Ecology: - distribution... and abundance... - 1 billion: ...to about 1850 - 2 billion: 1928 (about 78 yrs) - 3 billion: 1960 (about 32 yrs) - 5 billion: 1987 (about 15 yrs/billion) - currently 6.5 billion - adding about 80 million people each year

  19. Human Ecology: - distribution... and abundance... Born 1928 (3x)

  20. Human Ecology: - distribution... and abundance... Born 1928 (3x) Born 1960 (2x)

  21. Human Ecology: - distribution... and abundance... Born 1928 (3x) Born 1960 (2x) Born 1987 (1.5 b)

  22. Human Ecology: - distribution... and abundance... and interactions with the environment Mountaintop removal in West Virginia

  23. Human Ecology: - distribution... and abundance... and interactions with the environment some numbers to think about... and maybe remember...

  24. Human Ecology: • - distribution... and abundance... and interactions with the environment • 40% of primary productivity (E) Iowa - arrow pointing to forest fragment

  25. Human Ecology: • - distribution... and abundance... and interactions with the environment • 40% of primary productivity (E) - massive extinction is a predictable consequence 1 10,000,000

  26. Human Ecology: • - distribution... and abundance... and interactions with the environment • 40% of primary productivity (E) - massive extinction is a predictable consequence • 50% of the freshwater on the planet
