Endangered Species (polar bears)
- First animal to be considered endangered
- It is one of the top pretetors on the food chain, some times the seals that they eat have toxins and when the bears eat them they kill the bears.
Coral Reefs and Bleaching:
- Reefs comprise .02 percent of oceans
- sixty percent of them have been threatened by humans
- eleven percent has already been damaged
The Great Barrier Reef is the world's largest
- Thirty three percent of it is a no-take area to keep people from taking some of it
- It is at risk from increasing water temperatures, causing the acidity to change and bleaches the reef white until it dies.
- If we lose the reefs, we would loose much of our fish that live there and keep the ocean alive, they also protect coastal areas from tides and storms.
Carbon Dioxide in Ocean
- Global warming is likely to increase levels of Carbon in the Ocean
- Coral Reefs grow very slowly, and take forever to grow
