7 Billion: It's getting crowded in here! (extended special for Radio National's Population Weekend)

High density living is great for the environment, right? But what does it do to our heads and hearts? The Australian psyche was moulded by the myth of the 'wide brown land', so what might life packed like sardines look and feel like? With the world's seven billionth person about to be born, can we learn from the Asian megacity experience? And will we still be sharing a cup of sugar with our neighbours? As the population debate gets mental, we're going in search of the soul in urban sprawl. A forum featuring Bernard Salt, Kim Dovey, Helen Killmier, and Sein-Way Tan, hosted by ABC Radio National's Natasha Mitchell at The Wheeler Centre in Melbourne.
