Ecology of Transgenic Crops
Genetically engineered plants might generate weed problems and affect nontarget organisms, but measuring the risk is difficult

Acknowledgments
The author thanks Kay Peterson of the USDA for her rapid response to requests for copies of petitions and Michael McKee of Monsanto for providing information about nontarget studies. In addition, the author thanks Peter Kareiva and Polly Goldman for comments on an earlier draft.
