I'm not a vegan myself, I'm not arguing that animals aren't displaced to grow the food that vegans eat and I'm not saying that there aren't environmental issues with some of the specific crops used to make vegan food - but raising animals for food does have a big environmental impact. There's the land the animals live on, and then there's the land used to grow the food for the animals to eat. You need a lot more crops to raise enough animals to feed a human than you do to feed a human directly on a plant-based diet, that's just a fact, and native animals get displaced to free up the land to do so.

That's just untrue from two standpoints. First: not all agricultural land is created equal. In three broad categories in descending order of soil fertility, there is "suitable for crop growing", "suitable for trees", and "nothing else will grow here particularly well except for grass so we'll put some grazers here I guess". The third category cannot be bumped up to prime crop land without metric tons of fertilizer, which is *also* bad for the environment, or putting greenhouses there with carefully controlled climates that take a ton of electricity. Second: the idea that "the same amount of land that can grow 1kg of beef can also grow 10kg pf veggies" is based off the idea that land is the limiting factor, and not water. In most of Europe, that is probably correct. But the whole world is not Europe. There are whole entire swathes of the planet with tons of land but very little water. And cows, goats, and sheep are excellent at ruminating the moisture out of brambly little plants not fit for human consumption. I agree that the overconsumption of meat is damaging to our environment, but I strongly disagree with your apparent assertion that meat eaten in moderation cannot fit into responsible land management. We've been doing that for millennia, and livestock didn't become a main source of air pollution until the post-war economic boom made people eat more and more meat. Two side notes: 1) even if we woke up tomorrow and all the livestock on the planet disappeared, they would just be replaced with massive monocultures like what's already happening to fit vegans' lifestyles. Which are *also* horrifically bad for the environment and are a famine waiting to happen. 2) literally not everyone is physically capable of becoming vegan. The three main sources of protein in vegan diets are also three out of eight of the most common food allergens (peanuts, tree nuts, and soy), not to mention the people intolerant or allergic to gluten and the people with issues digesting specific nutrients from plant-based diets (I have personally been told by a GP, a nutritionist and a phlebotomist to please eat meat semifrequently because my body already hates absorbing iron there, for example, and plant-based irons are absorbed slower). Are all of those people supposed to just die?

OP, soy is one of the worst...? And what do burger cows eat? A crapton of? Soy.
