What is the Green Belt?

The Green Belt, often decried as sacred land never to built upon. In this video I explore some arguments for and against the green belt as a mechanism for controlling urban sprawl and look at its successes and failures. Green Belts are as old as cities themselves and we are now living in an era where more of us are moving into the cities. The question of how we live sustainably, not just environmentally but also economically, socially and in terms of our well being is becoming ever more important.
