Personally, I want urbanization to fight against obesity - walkable cities produce a lot more natural and casual physical activity than living in suburbia and needing to drive three miles to pick up a can of coke. Good urbanization also, I believe, would discourage myopia. I've spent the past few months living in Barcelona and nearly everything here happens outside in the sun - going for dinner, meeting friends, playing a board game... people tend not to do as much inside under florescent lights when usable, comfortable, and safe outdoor spaces are available.
