Carbon dioxide is actually a very important greenhouse gas, and an important part of the process that makes Earth so pleasant to live on. The amount being generated, however, started to outstrip the Earth's abilities to handle it in the 20th century.nd CO2 is a greenhouse gas as is oxygen, water vapor and nitrogen. CO2 along with the other trap heat between the earths crust and the atmosphere, not letting it escape. This in turn raises the temperature of the earth.
Forests play a huge role in the carbon cycle on our planet. When forests are cut down, not only does carbon absorption cease, but also the carbon stored in the trees is released into the atmosphere as CO2 if the wood is burned or even if it is left to rot after the deforestation process.limate change is because of a build up of carbon dioxide in out atmosphere and if we carry on cutting down the main tool we have to diminish this CO2 build up, we can expect the climate of our planet to change dramatically over the next decades.
