Coming up today... Author and environmental activist Derrick Jensen joins us to discuss his thoughts on the urgent need to dismantle industrialised society.

John Stewart who was ranked as the UK's #1 environmental activist in the Independent newspaper is back on the show. Last time he discussed the aviation industry, this time it is rapidly sprawling road networks.

Also NASA suggest industrial-civilisation may only have a few decades left, US scientists intervene on the urgent need to tackle human caused climate change, as the south-east braces itself for the construction of two new cities Jonathan Porrit warns that environmental groups have a problem with population, and as environmentalist Al Gore confirms he plans to eat "vegan" for life, meat and dairy are suggested to be as dangerous for human health as cigarettes.
