I bet you live in San Francisco :D /jokes a side; for you to be healthy without eating meat you need to eat a large variation of plants, it's not only one, it's not only one meal by day. It's not easy and have a great impact in nature too, meat have all we need and is simpler. Also, humans that are fed only with meat are able to eat once a week (or less).
Again, please share the studies to back up your claims. You're either trolling or just very poorly informed and spreading misinformation without checking it.
And how do you reconcile the fact that animal agriculture is a large contributor to ecological destruction and greenhouse gas emissions. Here is the result of a 5 year Oxford Uni study that recommends adopting a more plant-based diet to reduce your personal carbon footprint[0]
