Is there a real community of interest on the state of the environment that transcends national boundaries? An answer to this vital question will ultimately determine the success or failure of initiatives where international co-operation and co-ordination are essential, such as atmospheric or water pollution controls. Shades of Green, volume two of the ISSP (International Social Survey Programme) series, analyzes data from identical surveys conducted in 22 countries and tackles a wide range of attitudes and priorities. Expectations of government in terms of environmental protection, a comparison of Canada-U.S. results, the level of knowledge on environmental issues from country to country, the perceived role for science in solving ecological problems, and attitudinal differences between the West and states of the former Soviet Union - these issues have serious implications for the environmental movement and government policies worldwide.
