The article that I linked above looks at how much cropland we'd need to feed the entire world population if we gave up on farming animals completely. It turns out that we would end up with about the same amount of cropland, but that's only to match the current production in calories (and nothing else). Assuming the human population continued to grow, we'd have to use even more land to grow crops. There is of course a lot of pasture that could be turned back to forest, or left to turn back to forest, on its own. But not all pasture is ancient forests. I have no idea how much forest we would regain by ceasing to feed animals on pature.
