GM corn being developed for fuel instead of food

Suzanne Goldenberg in the Guardian (UK): US farmers are growing the first corn plants genetically modified for the specific purpose of putting more ethanol in gas tanks rather than producing more food. Aid organisations warn the new GM corn could worsen a global food crisis exposed by the famine in Somalia by diverting more corn into energy production.

The food industry also opposes the new GM product because, although not inedible, it is unsuitable for use in the manufacture of food products that commonly use corn. Farmers growing corn for human consumption are also concerned about cross-contamination. The corn, developed by a branch of the Swiss pesticide firm Syngenta, contains an added gene for an enzyme (amylase) that speeds the breakdown of starches into ethanol. Ethanol plants normally have to add the enzyme to corn when making ethanol.

The Enogen-branded corn is being grown for the first time commercially on about 5,000 acres on the edge of America's corn belt in Kansas, following its approval by the US Department of Agriculture last February. In its promotional material Syngenta says it will allow farmers to produce more ethanol from the corn while using less energy and water.

Meanwhile, campaigners say the corn will heap pressure on global food supplies and contribute to environmental degradation. They argue Enogen will lead to an increase in the amount of food crops going to fuel, leaving less for human consumption and leading to food price rises. That will lead to food price rises on the global market. "The temptation to look at food as another form of fuel to use for the energy crisis will exacerbate the food crisis," said Todd Post of Bread for the World, a Christian anti-hunger organisation....
