Farmers need land so they are burning huge sections of forests all around the world. As you can probably imagine this is not good for the wildlife that lives there. Not all fires are purposely started some are natural and climate change
is making it worse by making it hotter and dryer.
The fires could grow out of control. Or even if they don't, the animalsthat live there could quite easily be trapped and killed by the fire! This in some ways is worse than chopping down trees - at least when you chop down trees you get resources.
