Homo Urbanus

According to the UN, half the world's population will soon live in cities. This comes as no surprise when you consider that we're well into the Information Age, we're consequently placing more value on culture itself, and cities physically represent our cultural centers. A higher population density means a higher rate of meme-churn (did I just coin a new term?); a higher/faster rate of cultural evolution. More people tend to yield more ideas, simply put. More complicated, however, is the urban sprawl that ensues.
