Not the person you originally replied to, but eating plants directly would at least be a sort of harm reduction in that case. It takes a lot more plants to raise non-human animals than to just use plants directly. This is also a big part of why the environmental impact is so high for meat, dairy, etc.

1 kg of meat requires 2.8 kg of human-edible feed for ruminants and 3.2 for monogastrics
