    85% of soybeans are pressed for oil for human use.

    and those water use stats include things like the water it takes to raise feed crops. it would make sense, except that we mostly feed livestock plants or parts of plants that people won’t eat. for example, we raise cotton for textiles, and the seed would be industrial waste if we didn’t feed it to cattle. why do we count the water used to make jeans in the water used to make beef? it’s just dishonest.

            there is no reason to think that the land would be deforested, nor even that it would not have been deforested for some other reason, if everyone were vegan.

                    the nature article only talks about the impacts of producing the various foods in the current circumstance. if people shifted to eating less meat, then circumstances would be different, but it’s not clear that the environment would actually benefit at all.
