Worldwide soya is mostly grown to fatten up animals around 77-90%
Globally 90% is for animal feed according to greenpeace.org.uk/challenges/soya/
Globally 77% is for animal feed according to ourworldindata.org/soy
Fishing is destroying the oceans. Why not stop eating fish to help this?

Not all Vegans eat soya.
Humans don't have to eat soya.
Vegans make up a fraction of the world population. So if soya is the problem, it's not the Vegans eating it.
If the world went Vegan the environment would improve. - Supporting evidence
