Deforestation

Deforestation caused by humans contributes to one third of all carbon dioxide and 25 to 30 percent of all the green house gases released into the atmosphere.

Carbon dioxide in the atmosphere increases for a couple of reasons but one of the main factors, which increases carbon levels, is the decay of woody material. The only way in decreasing the level of carbon dioxide is through plant life. Plants and trees absorb the carbon dioxide from decaying plants and trees. With a decrease in trees and plants, due to deforestation, it is much harder to decrease the levels of carbon dioxide. This means that the carbon levels will increase due to the decrease of plant life to keep the carbon dioxide levels normal. Also decaying plants produce methane, which is a green house gas that is more harmful to the environment that carbon dioxide. These green house gases that are let out in the atmosphere leads to an increase in temperature and climate change, which is global warming.

Deforestation has a great impact on the environment and contributes to global warming. With these facts we should all acknowledge how this will harm the environment and together we have to make a change by decreasing deforestation.
