What effect might the destruction of the rainforest have on climate?
When forests are cut down, much of that stored carbon is released into the atmosphere again as CO2. This is how deforestation and forest degradation contribute to global warming. The consensus among climate scientists is that CO2 from tropical deforestation now makes up less than 10 percent of global warming pollution.
Why is rainforest deforestation a problem?
The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging. … Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world’s biodiversity.
