When President Theodore Roosevelt came to east Africa in 1909 an estimated 300,000 rhinos roamed the region. Now there are perhaps 2,000. The problem is not that the rhinos are half-blind, lumbering, and often infertile—which they are. It is economic: the ornamental and medicinal value of rhino horn makes it hard for the rhino to pay its way alive.
