Whenever I do, it gets flagged, but I'll give it another shot. Go learn about farming. It's the most environmentally destructive human activity. Go learn about how much land we would have to destroy in order to feed a terrible vegan diet to humanity. Trillions of animals ( insects, rodents, etc ) are killed to protect vegetation. Not to mention other animals like rabbits, deer, birds, etc that have to be wiped out. After all, you don't want a herd of deer or even elephants trampling on and eating your vegetation.
"Which means humans and wildlife are competing for fertile land for production of food and vegetation,” said Kitso Mokaila, Botswana’s minister of environment."

Pretty much anywhere you have farms, you have to wipe out the animals to protect the vegetation. Whereas vegetation for livestock can be grown in poor quality land ( nebraska, dakotas, etc ), the crap that vegans eat cannot be grown there. Not only that, the crap that vegans eat - processed nuts, avocados, etc are extremely water expensive.
Ideally we'd all be hunter gatherers - pretty much 0 environmental footprint as you eat what mother nature provides. But given the human population that's unrealistic so the next best thing is livestock + vegetation ( omnivore diet ). The absolute worst thing is vegan diet as it is a terrible diet for humans, but it's also devastating for the environment as you'd need find a ridiculous amount of fertile land in warmer climates all over the world to destroy and farm since we can't raise the garbage vegans eat where we grow animal feed.
Also, if the world shifted to a vegan diet, then we'd have to get rid of pets since we'd have no source of meat for our cats, dogs, snakes, etc.
Vegans think the vegetation they eat drops down from heaven like manna. Nope, not only are trillions of animals killed to farm garbage for vegans, harvesting and processing also kills tons of animals. So much so that every bowl of salad is guaranteed to have many animal parts in them.

So oddly enough, a lone vegan eating a bowl of salad is eating more animals than a family having steaks for dinner.
Also, humans aren't herbivore. Forcing humans to eat a herbivore diets is as wrong as forcing a herbivore to eat a carnivore diet. It's unnatural and deep down evil. But that's why some people support it so passionately I suppose. Vegans, anti-vax, flat earthers, etc are all the same type of people.
