We have always kept the seed of the best of this years crop to plant for next year, and thus the crop improves. Maybe a bee or a wasp, will cross pollinate a plant by chance, but what are the chances of a fish swimming through your glasshouse, or grain field? Once you have created a transgenic organism, one that sets seed, then you make it possible for these genes to be absorbed by other plants. If you make a crop immune to roundup or some other pest/pesticide how long will it be before other plants acquire the immunity. What will happen to the birds, and other animals who eat this seed which contains new and possibly harmfull ingredients. It is a can of worms and I for one would prefer not to open that can. It is crazy in this day and age when farmers can crop 10 tons an acre, where before modern fertilisers he could only harvest 3 tons for us to be inventing yet more ways to increase yields. In the EEC farmers are paid not to cultivate fields, and still the yields increase, and the food mountains grow. Where will it all end?
