In an age of climate crisis and political confusion, ecology seems to offer clear answers to urgent questions about the current global predicament. Yet ecology has always been politically ambivalent. Environmental ideals appeal to radicals and reactionaries alike; ecological concerns can align with both the left and the right, including the extreme right. In Ecology Contested, Peter Staudenmaier examines the complex and conflicting politics of environmentalism with a critical eye, offering challenging perspectives on the historical, philosophical, and political dimensions of ecological engagement in a troubled world.
