  1. CONSERVATION BIOLOGY UNIT: Our resources under pressure… What’s happening?

  2. BELL RINGER #1 • OUR UNIT TITLE IS- Our world resources under pressure. What do we mean by this? And, what resources are we talking about? • Air • Water • Forests • Land • Biodiversity

  3. WARM UP  • WHAT IS BIODIVERSITY? • Biodiversity is the sum total of the variety of organisms in the biosphere • PEOPLE TALK ABOUT: • Ecosystem diversity • Species diversity • Genetic diversity

  26. FACTS ABOUT:Biodiversity ε Extinctions • Extinction occurs when there are no longer any living individuals of a species left. • There have been five periods of mass extinction's on earth 440m, 370m, 250m, 210m and 65m years ago. • Scientists estimate that currently, living organisms represent only 1% of all the species that have ever been (i.e. 99% have been and gone) • We are in a sixth period caused not by meteorites or deep ice ages, but by human resource uses - this process is super fast in contrast to all past experiences.

  27. TWO QUESTIONS TO KEEP IN MIND 1) WHY IS BIODIVERSITY USEFUL?2) WHY SHOULD WE CARE ABOUT IT?

  28. Ecosystem Diversity Equator WWF- 827 Terrestrial Ecoregion

  29. Species Diversity WWF- Species Database~450/827 Ecoregion’s in the Tropics
