My understanding is that the densely populated cities are the most sustainable form of living we do. It reduces carbon emissions because we need don't have to drive so far to get to the shops or work, and we can use public transportation, further reducing the carbon emissions. The housing gets expensive, because of demand, but it reduces destruction of wildlife habitat. http://www.citylab.com/work/2012/04/why-bigger-cities-are-gr...
