Why would Agriculture or land use cause global warming?
Human beings do not cause Global Warming! Duhhhhh! Our earth has had tens of thousands of Global Warming periods over the past millions of years – all without the help of man! Global Warming is just another name for CLIMATE CHANGE! If there were no human beings on earth we would still have climate change! Mars is undergoing Global Warming and as far as we know there are no human beings there to blame it on! No agriculture means no food which means no human beings and we still end up with climate change.
