Brown welcomes "population crisis"

Greens Leader Bob Brown has welcomed Dick Smith's new book venture Dick Smith's Population Crisis launched today in Sydney.

"I'm looking forward to reading it. Dick makes a great contribution to Australian debate about population and resource pressures in this age of consumerism. We may not always agree with him but welcome his courage, commitment and stimulus to get us all thinking about the big issues of the day," Senator Brown said.

"He's right that exponential growth is clearly not sustainable."
