Iowa’s Governor has used a national stage to defend the use of biotechnology in agriculture. Governor Tom Vilsack was a guest speaker yesterday at the National Press Club in Washington, D.C. Vilsack said the nation’s farmers face the daunting task of feeding an ever-expanding world population. He says biotechnology isn’t a new science, it’s simply quicker science. Vilsack says biotechnology began back in 1750 B.C. when food was first fermented to preserve it.Vilsack said federal regulators keep a close eye on research to keep any bio-tech products and processes off the market if there are dangers. He says few Americans are aware of the tests done on food.Genetic modification of plants and animals has been under attack, notably in Europe where some consumers object to food that’s been altered or changed through genetics or low doses of radiation to kill bacteria.
