Humans hog 83 percent of the Earth's land surface, a new report says. Scientists from the Wildlife Conservation Society and Columbia University have published a map that details the "human footprint" -- the land we use to live on, farm, mine or fish. The few pristine areas left for wildlife include the northern forests of Alaska, Canada and Russia; the high plateaus of Tibet and Mongolia; and much of the Amazon River Basin. "The map ... is a clear-eyed view of our influence on the Earth," the ecologist who led the report said.
