Germany's biofuel crop concerns

22 September 2012 Last updated at 17:36 BST

As food prices around the world continue to rise, environmentalists say the problem is being made worse by the increased amount of farm land being used to grow biofuels.

In Germany, shepherds say their traditional way of farming is under threat as meadows they have always used for grazing are being turned over to biofuel crops.

Meanwhile farmers who grow both food and fuel crops have found they cannot sell their food crops for a decent price, and can only stay in business if they sell it for fuel production instead.
