The environmental movement in the past few decades can be seen as having two somewhat separate strands, “green” and “brown” environmentalism. The green movement is more concerned with conservation of the remaining wild places; the brown movement is more concerned with cleaning up industrial pollution. The major national conservation organizations had a largely “green” agenda and were not very interested in grassroots local organizations that sprang up around toxic sites, such as the Love Canal Neighborhood Association in Niagara Falls, New York, and other Superfund sites. More recently a third strand, “white” environmentalism, has been delineated. Its main concerns are the dangers posed by newer biotechnologies such as the cloning of human tissue and genetically modified food crops (Pakulski and Tranter 2004; Stone 2002). Each of these environmentalisms tends to draw its membership among people from different strata of society as well as from people holding different values and ways of organizing
