Animals also die in a lot of vegetable farming too. Lots of small rodents, squirrels, birds, insects and so on grinded up by various farming machinery or poisoned from pesticides, and until we have replicators or scalable permaculture farming we will never escape that.

If 800 rats and fluffy squirrels die violently & painfully for the equivalent amount of veggie nutrition of one cow who is killed ethically, eating grass grown naturally, are their lives worth less? What is the ratio?
