My point is proven science, you didn’t ask for a source you just claimed the opposite, so you’re on the same footing as me.
Except for my point is obvious, between the methane and animal waste run off, the water required for animal agriculture, the waste products unused from meat production, and the fact that you have to grow even more plants to feed the animals instead of eating the plants directly, I don’t see why on earth you wouldn’t see how being vegan has a smaller footprint.
Read a scientific study in-between your theory, sometime.
