Explain how earth's natural atmospheric cycle of CO2 is out of balance due to human activity.?

usualy plants intake co2 at a similar rate that animals produce it. but humans are releasing huge amounts of carbon that was sequestered as oil coal and natural gas. basicaly we are releasing it faster than plants can take it in. problem being made worse by the fact we are destroying forests and their fore lowering the ability for it to be reabsorbed
