I've seen suggestions that livestock can actually be a key component to carbon sequestration, if done correctly. I think it was mentioned in the documentary Kiss the Ground, narrated by Woody Harrelson, but I may be wrong. I believe the gist was that no-till farming and managed grazing helps to save the topsoil, sequester more carbon dioxide, and make something like cattle farming effectively carbon-negative (ie, they're actually helping to mitigate climate change). I'd recommend watching if you haven't, it shows some compelling examples such as a farmer who's the only one in his area farming this way, and he's also the only one who's having successful harvests while being environmentally conscious.
Also, farmed livestock don't automatically exist in a "living hell". Factory farms, yeah, but a properly-managed ranch should have happy, healthy animals.
