Which would you prefer? A thousand people living freely or a hundred thousand people living in cages too small to stand up in?
Get outta here with pretending that big number = better. Those animals are raised in horrifying conditions explictly to be slaughtered. They wouldn't exist in the first place except for the cruelty and greed of the meat industry. We routinely acknowledge that there are 'fates worse than death' for people, but when it comes to animals people seem to forget that. With the ending of the meat industry, fewer animals would exist, but they would be much better cared for.
What? The entire point of veganism is that it is an entire order of magnitude more efficient than eating meat. Turns out all the land we use to feed animals we can just grow soybeans on instead. Speaking of which, you want amino acids? Wanna take a guess what has all the amino acids you need? That's right, tofu! It's widely recognized as the healthiest source of protein possible. That sets it apart from red or processed meat, which actively gives you heart disease and cancer.
Look, I'm sorry, but you're just wrong. If you want to eat meat despite the facts indicating you shouldn't, that's fine. Same as you can decide to smoke cigarettes and drive a Hummer. Just be aware that it's worse for both you and the entire planet.
