The majority of which is methane, which only has a 7-12 year life. Which means — unless for some reason you started eating way more animals than you did yesterday — that your emissions today simply replace your emissions from 12 years ago. In other words, it is a stable system, unlike carbon, which basically sticks around forever.
You must have been misinformed, they tear down forests to grow soya to use as feedstock (mostly for beef). Nothing to do with fake meat tofu, quite the opposite actually.
