Scientific and Public Perception of Plant Genetic Manipulation — A Critical Review

Abstract

Scientific views on the importance and potential risks of plant genetic engineering are summarized and the ecological and economic consequences of the large scale release of engineered crops is discussed. The difference between scientific risk assessment and the public's perception of risk due to modification of the former by outrage factors is explained. Polls, media, and literature sources show that the public supports plant genetic engineering activity, but has some concerns. These concerns fall within two categories: (1) it is risky, (2) it is morally wrong. Polls show a lack of knowledge about GE by the public and that outrage factors play a major role; their effects on perception are described in detail. Ethical considerations also exercise a powerful influence over GE's acceptance, but the complementary roles of Religion and Science are emphasized. Different attitudes to nature are described and it is concluded that if the world is to be fed and life support systems sustained, active management of nature is required.

Lastly, the need for scientists to communicate with the public and the basis of effective presentation is discussed.
