Much more land can be used for growing animals than for growing crops. And without animals there would be no dung so the only way to let crops grow would be chemical fertilizer (which is made of oil).

You’re talking about a different issue which is food shortages.
There is absolutely no shortage of arable land on earth, the problem is it isn’t evenly distributed but that’s an easy enough problem to solve if we actually wanted to solve it. The solution isn’t cattle.
It’s obviously not the solution because if it was the solution there wouldn’t be world hunger, you can’t feed millions of people on cow.
