Abstract
The widespread concern about the declining state of our physical environment is often accompanied by frustration about what to do to prevent or even reverse such deterioration. In the past, policy makers, legislators, and the general public have usually turned to scientists and scientific knowledge for answers. But recently, theorists and others have reemphasized the importance of culture in understanding the environment. In this article, this culturalist critique of scientific knowledge is discussed and is then related to the decision by Ontario Hydro to lay up seven of its nuclear reactors. This situation is used to illustrate the continuing relevance of scientific knowledge for addressing environmental concerns.
