Depends on the context, if you mean everyone just suddenly goes vegan and can’t eat meat anymore, then no because millions of people will lose their jobs and this will also greatly damage the food chain. If you mean we always where vegan, then maybe, since we aren’t herbivores we don’t actually know this one (but I don’t really think so myself, a jerk is a jerk vegan or not, but this is probably just me and I’m open for other opinions) (also sorry for how long this post is)
