Metrics details. South Africa has been growing first-generation commercial genetically modified GM maize since Despite a requirement for non-GM food, especially for export, there is no system for coexistence of GM and non-GM crop. Gene flow is a major contributor to commingling, and different distances of cross-pollination have been recorded for maize, using a variety of field-trial designs under different environmental conditions, with the furthest distance being m. However, these trials have usually been small plots and not on the scale of commercial farming. There are also no published data regarding the extent of cross-pollination for maize in South Africa, even after a decade of commercialization of GM.

This is helpful, until it is realized that it is not just hurting the pest insects, but also the pollinator ones. When genetic modifications affect insects like pollinators, they affect the entire ecosystem. If the number of pollinators drops, then the number of flowering plants and crops that grow will decrease. Any pesticide or herbicide that 's from the plant could injure organisms in the environment.
Case studies: A hard look at GM crops
Feed Your Mind Main Page. PDF KB. It is very likely you are eating foods and food products that are made with ingredients that come from GMO crops. Many GMO crops are used to make ingredients that Americans eat such as cornstarch, corn syrup, corn oil, soybean oil, canola oil, or granulated sugar.
In the pitched debate over genetically modified GM foods and crops, it can be hard to see where scientific evidence ends and dogma and speculation begin. But critics question their environmental, social and economic impacts. Researchers, farmers, activists and GM seed companies all stridently promote their views, but the scientific data are often inconclusive or contradictory. Complicated truths have long been obscured by the fierce rhetoric. Are they driving farmers in India to suicide?
