Answer: C) Most people assume that global warming is caused by burning oil and gas. But in fact between 25 and 30 percent of the greenhouse gases released into the atmosphere each year – 1.6 billion tonnes – is caused by deforestation.

Exactly how does deforestation create greenhouse gases? We need more information in this post.
I think it was because of how trees tend to trap CO2 and when they are cut down all that built up CO2 is released into the air?
All plants convert CO2 into O2. The less trees, the more CO2 aka greenhouse gas.
And I think most deforestation is only economically done by starting huge fires which release mass amounts of carbon.
