Pollution Metaphors In The Uk Biotechnology Controversy

consumer groups demand non-GM food, while supermarket chains try to provide `clean’ food, i.e. free of any GM ingredients; retailers seek a statutory tolerance threshhold of inadvertent GM `contamination’ , below which GM-derived food does not legally require a `GM’ label, and this request is accommodated in law; organic farmers protest that GM pollen may contaminate their own crops; environmental regulators enforce their own rules restricting the ̄ ow of GM pollen, even by taking violators to court; government advisors warn that GM crops will encourage farmers to spray broad-spectrum herbicides, which may `sterilize’ wildlife habitats, so the government designs ® eld trials to test this risk; yet NGOs denounce the safety tests for failing to prevent `genetic contamination’ of nearby crops.
