> But the environmental burden of even the current population is quite severe, is it not? Most people fall between the extremes of a moral bar they are trying to measure human behavior by or you accept that everything that happens in the universe is defacto natural. With or without humans (ie when Yellowstone pops), the environment will change drastically over many human lifetimes. Creatures (maybe humans one day) will change, disappear, and wipe out other species. I worry about that day, more than the possibility the california delta smelt have a right to exist.
