August 2008. African elephants are being killed for their ivory at the highest rate since an international ban on the ivory trade took effect in 1989 according to a new report. 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 elephant's 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 annual death rate that led to the international ivory trade ban nearly 20 years ago, said Samuel Wasser, a UW professor of biology. But the poaching death rate in the late 1980s was based on a population that numbered more than 1 million. Today the total African elephant population is less than 470,000.
