How might deforestation in china and other countries affect the overall climate of the earth

they will pollute the air even more in china and other countries and won't give us much oxygen

Besides contributing to the greenhouse effect, deforestation generates other negative impacts on society and the environment. Deforestation and burning also affect the local climate reducing the humidity in the affected areas and may affect the flow of rainfall in the territory.

Deforestation and forest degradation are activities that emit greenhouse gases (GHG), especially carbon dioxide (CO2), that cause climate change. According to the Intergovernmental Panel on Climate Change, the Forests and Other Land Uses sector accounted for 22% of global emissions from 2000 to 2018.
