Yeah, because there's more people in total. That doesn't mean people going vegan doesn't stop the growth of the meat industry.
Say 50% of people eat meat, and the other 50% are vegan. Then say the world population doubles. Now there will twice as many vegans, but there will also be twice as many meat eaters, and so meat production will double. But there's still only half the meat production that there would be if 100% of people ate meat. And if you could get that value to 0% percent, there would be no meat industry.
production determines availability. there is no reason to assume we could produce more meat than we do, given land and technology constraints.
meat production happened before trade. there is no reason to assume it will ever end.
Where do you think meat is going? Why do you think it was being produced before trade, for fun? And do you not understand the basic concept that less =/= more, and that less emissions is better than more emissions?
It's really not a hard concept to grasp, but go ahead and keep trying to hide your head in the sand and justify your consumerism while pretending to give a shit. I won't bother wasting my time on someone who apparently can't grasp basic math.
This strikes me as nonsensical. If one person stops eating meat then the meat industry will create less waste. Maybe not exactly 1 person less, but unless they literally trash all of the meat that person would have consumed, it must be less.
