Humans affect the carbon cycle by adding carbon dioxide to it when exhaling. Plants do the opposite and breathe in carbon dioxide.

Humans significantly affect the carbon cycle by increasing levels of CO2 in the atmosphere from the use of fossil fuels. People have also cleared so much forest that the ability of photosynthesis to remove CO2 has also been severely impaired.
