Hard agree. Also, realistically, what is this proposing? Should cities be totally artificial environments with bounded growth rings to demarcate human/animal boundaries? Even a totally paved artificial environment is an ecosystem: which animals are okay? If cities are not bounded, how do we justify expansion into "animal" areas? To be clear, I'm fully onboard with no-build nature areas in countries like the US where we have lots and lots of sparsely populated land. But, environmentally integrated building is almost surely the best way forward for preserving human health and in terms of long-term maintenance of an industrial civilization.
