There are already documented environmental risks from GE crops, including the transfer of engineered traits to neighboring crops, effects on non-target insects, impacts on soil ecology, and potential threats to endangered species, among others. The genetic engineering industry objects to restrictions on environmental release of GE crops, claiming that it is impossible to meet farmer and consumer demands to keep these crops out of the natural food stream. Pharm crops raise all these environmental concerns, with even higher stakes for the food supply and the environment.
