How the carbon cycle might be affected if we increased the extraction rate of fossil fuels.

Fossil fuels represent carbon storage areas. Carbon that is locked in these fossil fuels does not cycle through the Earth. When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide. The carbon is then free to cycle through the Earth and can upset the natural balance of the carbon available, changing the way that processes occur on Earth.
