> As unethical as eating soy from a deforested area

Exact. Soy monocultures are devastating for environment, is an evil league respect to pastures, that still hold thousands of species. Soy fields have one species for Km and Km. Period.

Pastures in areas that are naturally grassy is fine. Pastures that have been created by deforesting the Amazon are not at all ok (Brazil is the worlds largest exporter of beef - not all of that is Amazonian land, but a lot of it is).

Soy is often grown in deforested rainforest areas too. But as a sibling comment says, only 6% of soy goes towards direct human consumption. The rest is for animal feed.
