In prehistoric times, our ancestors began building shelters and planting crops in order to escape from nature's harsh realities. Today, we flee urban dangers for the safer, reconfigured world of suburban lawns and parks. According to Yi-Fu Tuan, people have always sought to escape in one way or another, sometimes foolishly, often creatively and ingeniously. Glass-tower cities, suburbs, shopping malls, Disneyland - all are among the most recent movements in our efforts to escape the constraints and uncertainties of life - ultimately, those imposed by nature.
