They also don’t seem to understand that mono crop agriculture has far more devastating cost on the land that any sort of animal farming.

Those corn & soy fields were extremely diverse forests, savanna’s, etc before everything was destroyed and leveled for their pesticide & artificial fertilizer doused fields

And even if you try to raise plants ethically, which I’ve tried - you have to introduce farm animals if you want to do it on any meaningful scale. They recycle nutrients like no other & the land needs them
