主播大秀

Are the makers of biofuels undermining that most crucial resource - the global food supply? We debate the issues with a leading biofuels advocate, Lars Christian Hansen, the European President of the biofuels supply company Novozymes and Doug Parr, a Senior Policy Advisor with Greenpeace.

Also, the 主播大秀's Rory Cellan-Jones reports from the town of Romford about a Chinese internet company sending round-the-clock Olympics coverage back home via an old converted youth centre.

And our regular Kenyan commentator, Wycliffe Muga, looks at how the rising trade between Africa and China has also spurred the increased illegal smuggling in animal parts, like rhino and elephant horns.
