I'm vegan now but I don't know, I probably wouldn't just because I'm starch based now so potatoes, yams/sweet potatoes, squash, above the ground veggies, other starch veggies, nuts, seeds, legumes/beans, fruits, bread, grains etc.
But I do eat vegan "meat" products twice a week just to not get bored so maybe it would be better than having real live animals and eventually it will be necessary if we are going to continue at the rate we're continuing. Our earth can't take it forever, eventually viruses will wipe us out if not climate change so we need to get on it. I can't complain about lab meat, it's far better.
