Taking Carbon out of the Atmosphere
Nature is constantly taking carbon out of the atmosphere. These processes are sometimes called carbon sinks.

   Photosynthesis
- Plants use photosynthesis to make energy and grow. They take carbon dioxide (CO2), sunlight, and water and turn it into oxygen and sugar. Large areas of plants like the rainforest help to remove lots of carbon from the atmosphere.
   The ocean - Ocean water does a lot to remove excess carbon from the atmosphere. Carbon dioxide in the air reacts with the sea water to make carbonic acid in the ocean. If there is too much carbonic acid, you may get acid rain, which is not good. However, some carbonic acid is good as it is used by sea organisms to make their shells. These shells will eventually become sedimentary rock like limestone.
