But the public outcry that resulted in that ban is absent today, and a University of Washington conservation biologist contends it is because the public seems to be unaware of the giant mammals' plight. The elephant death rate from poaching throughout Africa is about 8 percent a year based on recent studies, which is actually higher than the 7.4 percent...
