Maybe YOU don't have to eat animals to survive. What a privilege u you have that you live in a place where vegetation can be grown in your area or more likely shipped there cheaply(not free of harm to the environment or people\animals). But your experience is not universal there are places on earth that people live where that is not an option. And some of those people have been living there sustainably for 10s of thousands of years. Not to speak of people who's body needs meat to live because of some other reason. You can not eat animals and that's fine but it doesn't replace the science of how to stop environmental damage.

Obviously if someone needs to eat meat to live I'm not going to object. And people living sustainably and not just supporting the animal ag industry are also off the hook in my books.

But in regards to your weird vegetation stuff, I hope you're aware that the livestock are raised on vegetation and will typically consume more calories of feed than they provide with meat? This is a large part of why the Amazon is being deforested, it's to feed livestock, not vegans. The science on how to stop environmental damage is pretty clear on that one.
