We can't have control over all nature because we haven't been able to control weather - and I still don't get why really really large fans... - never mind.
But it must be instinctive in us to control other animals (except house cats, who obviously hold dominion over us). Some human must have been the first one to figure out that having a herd of something was a steadier source of food than hunting. That corralling that almost flightless bird was easier than searching for it or its nest.
So, in that way, we are superior to other animals in that finding nourishment is something we've made less random. I don't think I'm disconnected from the laws of nature, but I do think that animals with language are superior to animals without, animals that use tools are superior to those that don't, and that many animals on the planet are pretty much food for the animals above them in the food chain.
Veganism for health is one thing (even if I disagree that it's healthful), veganism for moral superiority shows a lack of research and a spouting of dogma. Someone is harvesting all those veggies, and they mostly live in poverty, get sick, and die younger than they might have.
