Isn't this "extinction" just natural selection? "Winner takes all" is a feature, not a bug of natural selection.
Even if you don't think it's a crime to destroy an ecosystem, it's extremely foolish given that we depend heavily on it for our survival. If we damage or destroy it, what will happen to us?

I'm sure one can find "beauty" in the paleolithic era as well, but if you were suddenly stuck living there, you'd find that free wifi is one of the last creature comforts you'd end up missing.
Does anyone have a good track record? Isn't utilizing natural resources to the detriment of the ecosystem as a whole a feature of human civilization?
