Yes, humans evolved to eat some meat in their diets at points in time where other foods were scarce. This does not mean that meat is something we should eat often or as a primary source of food. And it does not mean that we can't survive without it. In addition to the incomparable suffering that animals who spend their entire lives in factory farms experience, a few good reasons are: 1. It is the number one cause of global warming 2. It's one of the main causes of deadly health problems in humans (heart disease, cancer, obesity related diseases). 3. It's a big reason why people go hungry. You can grow way more food to feed people through plant based agriculture. When you allocate land to meat production, you deprive people of food. 4. The reason why 60% of the rivers in America are classified as "impaired" due to runoff. There are lots more reasons if you look and I suggest you do. Just because we've done something for a long time doesn't mean we should keep doing it. Wouldn't you say that the conditions of the world have changed considerably since we were hunter-gatherers a few thousand years ago? Well, we need to evolve. The very best thing you can do for the planet, other humans, and yourself is to eat less meat.
