The Carbon Cycle presents the following enigmatic problem: Rates of CO2 Production from Anthropogenic Sources do not equal the amount of CO2 in the atmosphere .

CO2 levels are lower than predicted.

What is absorbing the extra carbon?

Ecologists suspect the following carbon sinks:

1. Rain forests

2. Coral Reefs

3. Temperate (hardwood forest) zone

4. Open Ocean phytoplankton

5. None of these

There are forward looking companies that now replace all of their CO2 emissions for the year with an equivalent amount of trees to absorb it This is know as “Good Stewardship” of the Earth.
