Between 1990 and 2005 I was heavily embedded in the genetic modification (GM) debate, as a member of one of the key regulatory committees for ten years, and then as deputy chair of the Agriculture and Environment Biotechnology Commission (AEBC). AEBC recommended a public debate on GM crops, which reached 37,000 people through a variety of routes and excited a good deal of press attention. The result? Most people are uneasy, most scientists are not, and the economists thought there was little of consequence either way for the UK at that time. The effect on policy? Almost none.
