The U.S. Fish and Wildlife service did a huge disservice to science, wildlife and modern agriculture last month, when it banned the planting of genetically modified crops in the National Wildlife Refuge System.

We make this decision based on a precautionary approach to our wildlife management practices, wrote James Kurth, head of the refuge system, on July 17, according to the Associated Press.

Did you catch the key word? Its one of the most loaded terms in the vocabulary of regulation: precautionary.

On the face of it, precautionary sounds reasonable. While crossing the street, it makes sense to take a precautionary approach. Better safe than sorry.

In the jargon of government, however, precautionary carries a special meaning. When bureaucrats speak of a precautionary approachor the precautionary principle, which is a more common way to put ittheyre usually trying to justify the suppression of a new idea or technology as too hazardous.

We all want sensible regulations, of course. Yet we also know that regulations are often insensible, thwarting the interests of the public theyre supposed to serve. Have you ever filled out a pointless form? Or wondered if its a crime to remove a mattress tag? And dont get me started on the Environmental Protection Agencys attempt to control the amount of dust that farmers kick up as they drive their tractors.

For all of these inconveniences, however, the United States has avoided the predicament of Europe, where the precautionary principle has become a powerful force to strangle innovation. This is why Europe remains so far behind the United States, Canada, Brazil and many other countries in the area of agricultural biotechnology. Over there, obsolete regulations continue to oppose new technologies, even though the safety of GM foods is settled science.

Mr. Kurths precautionary approach raises an alarm: Hes not speaking the language of science or common sense, but rather adopting a bad phrase that has bedeviled Europe.

We dont need it here. Our trade negotiators dont need it either. Banning GM crops in certain areas is no way to persuade China, Japan, and other countries to accept our food exports.

It may seem odd that the chief of the National Wildlife Refuge System should feel the need to say anything at all about farming. Crops arent wildlife and a cultivated field is no refuge.

Farmers plant GM crops in some wildlife refuges with a specific purpose: They are better for the animals and the environment. The stronger stalks and larger corn ears provide more food for the wildlife during the deep snows of winter.

Yet Kurth has introduced a new prejudice into Americas web of farming regulations. He has granted the presumption that GM crops are too novel, too mysterious, and too risky to allow their use in some of the countrys most pristine spaces. He can cite no actual science to back up his biasbut then, the precautionary approach never has been about science. Its about emotion defeating reason and fear trumping evidence.

If Kurth believes that GM crops pose a threat, he should have the gumption to say so plainly and present his evidenceand not hide behind words like precautionary.

The evidence in support of the health and safety of GM crops is in fact overwhelming. Thats why the American Medical Association and the National Academy of Sciencesamong many other groupshave supported the spread of biotechnology in agriculture.

Let me introduce another piece of evidence, from the very system that Kurth oversees: the Neal Smith National Wildlife Refuge, near Des Moines in my home state of Iowa. Its the countrys largest recreation of a tallgrass prairie ecosystemthousands of acres that look as they did when settlers arrived in the 19th century, complete with a thriving herd of buffalo.

This wildlife refuge thrives alongside biotechnology. In some areas, farmers grow GM corn and soybeans on one side of the road while badgers, elk, and pheasants wander around the other. The crops and animals coexist, in a model we should admire and emulate rather than doubt and dread.

The solution is simple: Lets throw precaution to the wind.
