I am co-directing The Planet, a documentary journey around the world, seeking an answer to how man-made changes are altering earth's environment, and what can be done to mitigate the damage. You can read more about this series at www.charon.se.

The first journey takes photographer Jan Roed and me to the slums of Nairobi early this February, one among a growing number of mega-cities that pose serious challenges for the survival of its inhabitants.

In mid-March, we will be in Oxford and London for a series of interviews. Norman Myers is a leading expert on biodiversity. Tim Halliday is the director of the Amphibian Task Force. He will tell us more about the reasons behind the rapid dissapearance of amphibian species around the world. And in London, Andrew Simms of the New Economics Foundation will tell us why environmental refugees are on the rise, and why they have yet to be granted refugee status.

Towards the end of April, we are flying to Jordan, Israel and Palestine to take a closer look at water resources in a region suffering from water scarcity. Nowhere is this more evident than at the Dead Sea, where the shoreline is receeding by a meter per year.

In September we are interviewing oceanographer Cecil Mauritzen in Norway about ocean currents in the north atlantic. Then we're off to Fraserburgh, Scotland, to tell the story of a traditional fishing town suffering in the wake of falling cod stocks.

Finally, in November, we're in Bombay, India. Here we're filming a news anchor at Zoom TV as she tells us about the new generation growing up at a time when the world's second largest country is revving up to challenge western consumers and economies. Also, we're visiting the countryside, where cotton farmers are finding themselves desperately trapped between the promise of ever greater crops and the cost of harsh pesticides and insecticides needed to realize that promise.
