1. Biodiversity 04

2. Significant ideas:
Ecosystem stability, succession and biodiversity are intrinsically linked

3. “The variety of life in all its forms, levels and combinations”
Includes:
ecosystem diversity, species diversity, and genetic diversity

4. Scientists have identified more than 2 million species
Scientists have identified more than 2 million species. Tens of millions -- remain unknown
The tremendous variety of life on Earth is made possible by complex interactions among all living things.

5. There are 3 components of biodiversity
Diversity of genes Cheetahs are on the edge. Approximately 10,000 remain in Africa. Less than 300 remain isolated in Iran.
other species are so scarce
that they only survive in captive
breeding programs

7. There are 3 components of biodiversity
Habitat
Variety habitat in an ecosystems Each one is different, with its own set of species living in it.

8. Biodiversity has Intrinsic Value

Intrinsic Value = Something that has value in and of itself

9. Biodiversity also has Utilitarian Value
Utilitarian Value = the value something has as a means to another’s end.
Utilitarian values include:
Goods
Services
Information

10. What do we get from biodiversity?
Oxygen
Food
Clean Water
Medicine
Aesthetics
Ideas

11. Should we be concerned about biodiversity?
What we know: The Earth is losing species at an alarming rate
Some scientists estimate that as many as 3 species per hour are going extinct and 20,000 extinctions occur each year.
when species of plants and animals go extinct, many other species are affected.

12. Threats to biodiversity
HIPPO Dilemma
Habitat Loss Introduced Species Pollution Population Growth Over-consumption

13. Biodiversity Hotspots

14. Provide formal documentation of the world’s known biodiversity (living or dead)
Museums, Zoos, Arboreta, Botanical Gardens, Public and Private Research Collections

15. Education
