In the open �pollen from� crops could pollinate another related plant. If they� with their� relatives, there could be the danger of creating . And if they �with non GM crops on� farms for examples, the farmers could not .
The first commercial products of genetic engineering were . It�s mainly the� that �the benefits. Now� in Europe and many other parts of the world are developing new products designed to be of direct benefit to the . Many of these research advances will be used in� where there are potentially large enough markets for the new products.
