Vegans don’t eat animals for the sake of the animals, because they believe killing them unnecessarily is morally wrong.
Saying you’re only going to eat animals once a day is like saying you’re going to halve the amount of violent crimes you commit and expecting praise for it.
It depends on wether you’re actually concerned about the animals, or about yourself.
If you’re concerned about the animals, 100 people reducing by 10% is exactly as good as 10 people reducing by 100%. The difference is, 10 people don’t have to feel guilty. But no animal benefits from that.
Those 100 people would still be eating 90% as many animals as they were before. People don’t need to eat animals to live, so expecting praise for eating 10% less is pretty funny.
It’d be like a criminal deciding to decrease the amount of crimes he commits by 10% and expecting people to encourage and praise him.
