Nevertheless, there are certainly a number of worrying possibilities. For one, maizes are being developed to contain antibacterial properties. It is feared that if transferred to bacteria they could become resistant to antibacterial drugs. .

             Advances in GM technology may also yield advances in other areas of science. Experimenting with DNA, genes and cells may aid research into human DNA. For example, in Texas scientists found a chemical compound in the plant borage that produces gamma linolenic acid, which has been found to reduce heart attacks caused by cholesterol. Theoretically, this gene could be transferred to crops producing lipids, making fatty foods such as margarine and ice cream healthier and safer. .

             There are also environmental arguments used in support of GM foods. Producing GM tomatoes uses less energy and water; herbicide-resistant crops reduce the amount of herbicide needed so it can be sprayed less frequently and intensively; pest-resistant cotton has reduced the use of pesticides on cotton crops in the US by up to two thirds. On the other hand it is thought that making farming more efficient may accelerate the damage to wildlife already done. At present, herbicides and pesticides have reduced numbers of grey partridge by more than 50% and removal of field margin and hedgerows has led to a decrease in populations of sparrows, skylarks and reed bunting. .

             It is evident that we must look at the impact of GM products on other organisms to provide a true assessment. Cross-pollination is a major worry, as it would cause non-GM crops to be 'contaminated" with GM crop genes. Surrounding GM crops with plants of other species would significantly reduce this risk of cross-pollination but the danger is still there. Boundaries between species have been established though millions of years of evolution and the worry is that these barriers will be destroyed with GM technology, leading to unpredictable events.
