While I agree with you about the ethics of our current methods for raising animals, I disagree that veganism is the answer. First, animals are a necessary part of ecosystems. For example, ruminants control grass growth, and they effectively transform energy in those grasses into a form that ultimately supports an entire food chain. If you eliminate ruminants from grassland, you lose insects, which feed birds and rodents, who feed larger predators, and so on. Controlling grass growth also leads to more plant biodiversity, which tends to further increase animal biodiversity. Second, animals are a great way to "recycle" food waste into delicious meat and fertilizer. Pigs and chickens are perfectly happy consuming things we find completely unpalatable. We use a lot of resources growing food specifically for these animals, while simultaneously throwing out a ridiculous amount of food grown for humans. Pretty silly. Ultimately, animals can be raised in an ethical and environmentally sustainable manner. This might entail a significant increase in the price of meat, but that's alright. The current low price of meat is something of a historical anomaly anyhow. As for health, almost all the blue zone diets include a small amount of meat (about 4oz a day).
