I'm all for reducing our overconsumption, but asking everyone to give up their cars and homes and get bikes/apartments doesn't make sense outside of big cities. Of course, some people will argue that everyone should move to cities--it's true that cities are more space efficient, but it would be immensely depressing both literally (cities are associated with significantly increased levels of depression and other mood disorders) and figuratively regarding the loss of cultural and lifestyle diversity. Perhaps most importantly, this is never actually going to happen, so maybe we should just focus on minimizing the volume of useless, toxic garbage we import from China (which relies on subsidies in the form of pollution and slavery).
