1 Biogeochemical Cycles: Oxygen Carbon Sulfur Nitrogen Phosphorous Calcium

2 Oxygen Cycle Brazil’s forests produce 40% of the earth’s atmospheric oxygen

3 Oxygen Cycle Image obtained from

4 Oxygen Cycle

5 Depletion of ozone leads to ecosystem health risks

6 Carbon Cycle Temperate rainforests store vast amounts of carbon, both above and below ground.

7 Carbon Cycle Brazil’s rainforests re-cycle carbon faster than any other ecosystem.

8 Carbon Cycle Today, the earth’s atmosphere is accumulating CO 2 faster that it can be sequestered. vrs Carbon sink Carbon stink

9 Carbon Cycle

10 Carbon Sinks: 1. Marine viruses and phytoplankton 2. Forests 3. Coral reefs

11 Carbon Cycle The earth’s “core” temperature is rising

12 Nature Is “Re-shuffling” The Deck As The Environment Changes
