Anker has written a ruthlessly honest political and cultural history of ecology, setting it firmly in the world of nineteenth-century colonialism. Illusions vanish here: turn of the century ecology did not stand for a pure pacifism or an eden of natural harmony. Instead, we find that both the liberal mechanism of British ecologist Arthur George Tansley and the holistic ecology of South African statesman Jan Christian Smuts were both firmly built upon nationalism--and a nationalism that mattered a great deal, militarily, racially, and socially. This is important work and a riveting read.
