Seven Billion: It’s Getting Crowded in Here!


Event Status

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 is 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.

Hosted by Natasha Mitchell and featuring Kim Dovey, Helen Killmier, Bernard Salt and Sein-Way Tan.

Presented in partnership with ABC Radio National.
