I always think it's interesting to view meat production through the lens of history.

Goats or sheep can be raised on land that's completely unsuitable for farming. Pigs and chickens can recycle food-waste into usable protein.

You can make an argument that modern feedlots aren't great for the environment, the animals, or our overall health. But it's a big jump to go from that to "all meat is bad for the environment".

Even best case emissions of meat production are higher than the worst case emissions of plant protein

> Many argue that this overlooks the large variation in the footprints of foods across the world. Using global averages might give us a misleading picture for some parts of the world or some producers. If I source my beef or lamb from low-impact producers, could they have a lower footprint than plant-based alternatives? The evidence suggests, no: plant-based foods emit fewer greenhouse gases than meat and dairy, regardless of how they are produced.
