For all those replying with "well yes, we already knew this".
Yes, but now you have the numbers to back up the conclusions you've already drawn.
Of course food produced from plants will be environmentally better than those made from animals, but now, next time you see someone actually doubting that, you can rebuff them with numbers and science.
But those numbers already existed. Those conclusions weren't drawn up out of nothing.
If 70% of the food we cultivate goes directly to our livestock, then we could only ever eat 30% of it ourselves. Meaning, for something that takes up 1/3 of our plate, we use almost 5 times as much resourses just to feed it as either of the other 2/3.
