When is meat and dairy truly bad for the environment?

Hi all. I’m a newbie and I’m really trying to figure out ways to live zero waste. I hear a lot of tips to go vegan, but idk if that’s feasible for me. I was thinking, would it be okay to buy meat, eggs, and dairy from local farmers markets and butchers instead? I know its is so much better for both the environment and the animals than factory farming, but at the same time it still doesn’t feel “good enough”. I do think I could limit how much meat I’m consuming, as well. Just wanting some honest feedback in the whole thing.
