Bringing policy relevance and scientific discipline to environmental risk assessment for genetically modified crops

Abstract

Although public opinion is important in deciding what is valued by society, governments have determined that scientific expertise is required to evaluate potential environmental effects of genetically modified (GM) crops. We suggest how to evaluate rigorously the environmental effects of GM crops in the context of a scientific investigation. Following a disciplined scientific approach to environmental risk assessment (ERA) for GM crops should help resolve controversy in identifying and addressing risk.
