1. PPT Lecture: Vanishing Species

2. Slide 2 - Biodiversity Bio = Life Diversity = Different # of different species in an area.

3. Slide 3 - Stop and Think. What would have a greater biodiversity
Slide 3 - Stop and Think! What would have a greater biodiversity? A tropical rain forest or a desert? Pretend both are equal in size.

4. Slide 4 - Stop and Think Again
Slide 4 - Stop and Think Again! What country has the greatest biodiversity of mammals?
Canada = 163
United States = 367
Mexico = 439

5. Slide 5 - Terrestrial Biodiversity Tends to increase the closer an areas is to the equator because it is warmer. Tropical regions contains 2/3 of all land species on Earth!

6. Slide 6 - Stop and Think. What would have a greater Biodiversity
Slide 6 - Stop and Think! What would have a greater Biodiversity? The small island of Maui or the bigger island of Iceland?

7. Slide 7 - Importance of Biodiversity Nature – Life depends on lIfe
Slide 7 - Importance of Biodiversity Nature – Life depends on lIfe! Humans – Medicine, Oxygen, Food!

8. Slide 8 - Loss of Biodiversity Extinction – Disappearance of a species
Slide 8 - Loss of Biodiversity Extinction – Disappearance of a species! Endangered Species – When a species is close to extinction! Threatened Species – When pop. of species declines rapidly

9. Slide 9 - Threats to Biodiversity
Habitat Loss
Habitat Fragmentation
Habitat Degradation

10. Slide 10 - Habitat Loss Habitat = Address Destroying habitats for buildings (businesses and housing)

11. Slide 11 - Habitat Fragmentation Fragment = Broken Piece To break up or separate a habitat!

12. Slide 12 - Habitat Degradation Degrade – Worsen To make a habitat worse by pollution!

13. Slide 13 - Purpose of Lecture Conservation
Slide 13 - Purpose of Lecture Conservation! Conserve – preserve or maintain the quantity and quality of habitats!
