- Trees absorb carbon dioxide from the air, which can increase greenhouse gases.
- the gases which are responsible for causing the greenhouse effect, e.g. carbon dioxide
- It can be inferred that carbon dioxide and methane are largely responsible for the increased concentration of greenhouse gases.
