"The Great Escape: Gene-Altered Crops Grow Wild"

"Throughout North Dakota, little yellow flowers dot thousands of miles of roadsides. These canola plants, found along most major trucking routes, look harmless. But they are fueling a controversy: They prove that large numbers of genetically modified plants have escaped from farm fields and are now growing wild. About 80 percent of canola growing along roadsides in North Dakota contains genes that have been modified to make the plants resistant to common weed-killers."
