If an animal does work to improve an ecosystem, how is that wasteful? I'm not sure what part of "the animals are beneficial" you're missing. We don't need to stop raising animals, we need to change our agricultural practices so that the animals are always just a single part of a larger system that is in balance.
It seems like your problem here is the capitalist society that demands a race to the bottom, pushing farmers to farm in a way that damages the earth. Perhaps you can redirect some of that simmering rage to the root causes of the things that you don't like.
