In some parts of australia, large areas of woodland have been cut down to create farm and grazing land. this practice is most likely to produce
a.
greenhouse gases.
b.
nuclear waste.
c.
acid rain.
d.
soil erosion.

Let's see the answer choices:
greenhouse gases - not likely, would cutting a forest produce greenhouse gases?
nuclear waste - only nuclear plants produce nuclear waste
acid rain - yes! There wouldn't be tress to clean the air, so the carbon dioxide and other substances would build up, that's your answer.
soil erosion - that would only be possible if wind or water were common.

Have a nice day! :)

It might be the second one
