I agree completely, which is why I'm a very strong proponent of sustainable urbanism and sustainable agriculture. Only thing I'll add is that reducing our car-dependent suburban sprawl will actually be good for the economy, not just the environment. Not only does the housing crisis knee-cap the economy (and the housing crisis is largely a consequence of our pursuit of car-dependent suburban sprawl), but car-dependent suburban sprawl is a fiscally unsustainable ponzi scheme. Building denser, more walkable and transit-oriented cities would save money, stymie the housing crisis, reduce inequality, and reduce emissions.
