Biodiversity is found everywhere but increases closer to the equator in warm, tropical environments like rainforests, coral reefs, and large tropical lakes. These areas provide rich habitats for diverse species. Habitat loss from activities like deforestation and dynamite fishing is one of the biggest threats to biodiversity as it can damage or destroy ecosystems. Fragmenting habitats into smaller pieces also negatively impacts biodiversity by restricting movement and resources for species. Air, water, and land pollution, including acid rain, further degrade habitats and environmental conditions.

1. Biodiversity Chapter 5.1

3. RAINFOREST

4. CORAL REEF

5. 1960 Experiment Larger the island, the more habitat and species it had This implies that the number of species depends on number of habitats

6. Importance of Biodiversity

7. Importance to nature Populations are adapted to live together in communities. They depend on one another.

8. Biodiversity brings stability to an ecosystem Otherwise, entire plants could be wiped out by pests

9. Importance to People

10. Loss of Biodiversity

11. Extinction Dodo Bird Passenger Pigeon

12. Endangered Species

14. Threatened Species

15. Threats to Biodiversity

16. Habitat Loss One of the biggest reasons for decline in biodiversity Dynamite fishing (imagine on grand scale) Disease and changes in water temp can damage or kill coral

17. Habitat Fragmentation

18. It presents problems for organisms that need large areas to gather food or find mates

19. Smaller the fragments  the less biodiversity

21. Edge Effect Edges tend to have great biodiversity because different habitats with different species are brought together

22. Habitat Degradation

23. Air Pollution Water Pollution Land Pollution 3 Types of Pollution

24. Acid Precipitation

25. Effects of Acid Rain

26. Ozone Hole Ozone = O 3 CFC’s = chlorofluorocarbons Began opening because CFC’s were emitted into the air through just about everything (hair spray, refrigerators, paint spray cans, etc…)
