THE CARBON CYCLE
this cycle shows how the carbon cycle works. To me and many others there are two cycles. One of the cycles is the Natural cycle in green. The natural cycle is how animals in-hale O2 and ex-hale CO2 and how trees and plants in-hale CO2 and ex-hale O2 and the circle it is in. The human cycle in blue is when animals, trees and plants die they decompose and turn into either soil or rocks and get buried and buried deep into the ground. Then people dig for fossil fuels like coal,oil and gas. Then we burn them and let to much CO2 into the environment and the trees can not take it all in because it is now a different form of CO2.
