People claim that more animals are killed in industrial agriculture than the animals that you would be eating instead. Like mice killed by threshers.

The flaw in that argument is that livestock animals are fed by industrial agriculture too, so by eating meat you are also responsible for more animals killed in agriculture than you would be by eating the produce yourself. It takes a lot more agriculture to raise multiple animals for one person to eat than it would to produce the amount of food they would eat otherwise.
