Elephants on the path to extinction - the facts

Some experts see the brutal killings of elephants not as a battle for a commodity, but for land. As the human population booms, so does demand for space. Poaching conveniently removes elephants from the land, leaving it open to development. This is a pattern seen across western Africa, where elephant declines have been most precipitous. By 2050, 63% of remaining elephant rangelands will be compromised by human encroachment.
