It is still too early to know what impact genetically modified (GM) crops are going to have. They are provoking opposition from experts and the general public in Europe and some developing countries. But many scientists argue that much of the criticism is ill-informed and sometimes "hysterical", fanned by an "irresponsible" media.
Supporters argue that the world desperately needs GM crops to ensure food security and sustainability, saying that they will produce higher yields of more nutritious food, with less use of chemical inputs. Opponents fear that the driving force behind GM crops is greed, not need.
This report looks at the debate over GM crops and their patents, suggesting that key to its resolution will be people's access to accurate, understandable information, not public relations hype or scaremongering.
