Many environmentalists, citing the adage “better safe than sorry,” argue that the “precautionary principle” should govern policy making meaning technology should not be used until it can be shown to pose no threat to humans or the environment. While the principle may sound reasonable in theory, critics argue it would be disastrous in practice. One cannot prove a negative.
A case in point is genetically modified crops. While some environmentalists want international Biosafety Protocols to embody the precautionary approach, scientists say their stance ignores the very real dangers of going without new technologies.
By stopping the use of artificial fertilisers, pesticides and biotechnologies, we would have to double the amount of land under active cultivation (see figure http://www.ncpa.org/ba/ba368/ba368fig1.gif). This would be disastrous for wildlife and native plants, as the lands most likely to be converted to agriculture are forests, rangelands and other wildlands in the relatively undeveloped tropics. By using biotechnology, proponents argue, we can provide the world’s future population with enjoyable, nutritionally adequate diets.
