I'd say the best solution of all would be to cut back massively on the eating of meat for a whole host of increasingly long list of bloody good reasons. It's not like there's not a fucking multitude of nutritious alternatives people could eat instead.
And I say that making improvements to land management, agriculture, and health systems would make a bigger difference than any of that. Malaria infects 200 million people a year. Becoming vegan won't change that.
