In a HARDtalk interview broadcast on 18 August 2009, Stephen Sackur talks to the environmental scientist James Lovelock.

James Lovelock is a celebrated scientist and writer.

He founded the Gaia theory - the idea that the planet acts like a single organism.

He has long spoken of man's "unsustainable exploitation" of the planet and the grave consequences that will follow.

Now ninety years old, he describes his latest book as a final warning on the fate of the planet.

Stephen Sackur asks him if humanity is likely to heed that warning.
