Dean Santos discusses her concerns for rapid urban development and the future of urbanism. She's keenly concerned about the fact that we are building 'mega-cities' in India & China and that the pace of development is speeding up while environmental pressures are increasing. Meanwhile, people are only productive when they have a decent place to live, and we're not always building an environment that promotes this. In China, the high rise slab/apartment & tower sprawl that exists - single use (living only rather than mixed use - living/shopping/working) is incredibly destructive to the environment and unpleasant to live in. We need to be thinking now about the legacy we're leaving for the future.
