Leaders of the G20 countries meet in the next few weeks to discuss what can be done about the global financial crisis.

A leading economic think-tank in the U.K. and the leaders of some European countries are saying the time is right for the world to invest substantially in renewable energy. And in fact we should be radically changing our economies to make them more sustainable.

A plan which helped pull the U.S. out of the Great Depression.

In Australia, Greens Senator Christine Milne has been a vocal advocate of the idea. She’s speaking here with our environment reporter Phil Stubbs.
