Risk, genetically modified food and the US/EU divide

Toke, Dave - In: International Journal of Green Economics 1 (2007) 3/4, pp. 407-418

The Genetically Modified (GM) food and crops issue illustrates some key contemporary differences between the EU and the USA on environmental issues. These differences have been parallel to the apparently stronger influence of environmentalists since 1990 on a range of issues in the EU, compared...
