If YOU take a flight, are you a planet-wrecking bastard? Are some bastards more hypocritical bastards than others? And why aren't politicians talking about Heathrow any more? We chat to brainy aviation campaigner Leo Murray, where we also learn things about Richard Branson's coconuts.

We've also time for a trip back to the early 80s for a warning about climate change that everyone ignored - and a chuckle at the Government's latest telling off about stinky air.
