An Oxford University study, published in the journal Climatic Change, shows that meat-eaters are responsible for almost twice as many dietary greenhouse-gas emissions per day as vegetarians and about two and a half times as many as vegans. 

Currently, livestock covers 45 percent of the Earth's total land. As a result, one-third of land is desertified.
