Genetically modified (GM) plants: questions and answers
The Royal Society commissioned a report into what people want to know about GM plants, and then drew on a panel of independent scientists.
What are genetically modified (GM) plants? Is genetic modification safe? Where are GM crops grown and eaten?
Food security is one of this century's key global challenges, as noted in our earlier report Reaping the Benefits, and due to the scale of the challenge, we should really think carefully before we rule out any technology that might help deal with the problem. The questions and answers given here are intended to provide a resource to those who are interested in what GM is, how it is used and potential future uses.
The Royal Society commissioned Ipsos MORI to find out what people want to know about GM plants, and then drew on a panel of expert, independent scientists to answer your questions. We hope that these answers explain the science behind GM and help you form your own view.
