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, it may lead to acid rain. 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.

Moving Carbon into the Atmosphere: at the same time that some processes of nature are removing carbon from the air, other processes are adding more carbon to the air. These processes are called sources. Decay - When plants and animals die they decay. When this happens, the carbon in their body will either be released into the atmosphere or stored in ground as fossil fuels. Respiration (breathing) - Every time you breathe you turn oxygen into carbon dioxide. This is true of every animal on Earth. Combustion (burning) - When plants, trees, or fossil fuels are burned, carbon is released into the atmosphere.
