Biofuel crops transform German farming

The shepherds of Germany are worried. There are still about 2,000 of them tending sheep on grasslands, plying their ancient trade and defying time and the intrusions of modernity.

But it is a losing battle. The pastures they and the sheep need are diminishing. The shepherds blame biofuels. They complain that meadows where sheep have always grazed are being turned over to the growing of crops for power generation.
