Writing for the journal Current Biology, researchers with the Wildlife Conservation Society have revealed that over the last 20 or so years, the Earth has lost 3.3 million square kilometers (1.27 million square miles) of wilderness – an area twice the size of Alaska and half the size of the Amazon rainforest – with the Amazon and Central Africa being the worst off. . . . “Globally important wilderness areas – despite being strongholds for endangered biodiversity, for buffering and regulating local climates, and for supporting many of the world’s most politically and economically marginalized communities – are completely ignored in environmental policy,”says Dr. James Watson of the University of Queensland in Australia and the Wildlife Conservation Society in New York.
