The GM food debate presents the classic conundrum for science because it involves powerful social, economic, political and moral issues. Here are a few of the fronts on which the GM war is being fought. Ethics Proponents of genetic technology say humans have been interfering with natural processes ever since selective breeding began.
Genetic engineering is simply an extension of breeding which is quicker and more precise.
Some argue that vegetarians should know if animal genes have been introduced into vegetables. Others argue the creation of new strains is permanent and, once released, may alter gene pools and ecosystems. The environment Proponents of GM crops say food can be produced in adverse conditions, will store better and need less chemicals and fertiliser. There is concern that allergens have been found in GM foods. However, GM proponents say the risk is low and that regulatory tests have picked them up.
