"...Knowlton argues that, in this instance, killing one black rhino will protect the species throughout Namibia and that this idea is supported by scientists and conservationists around the world."
"Knowlton says the Namibian government has identified a handful of black rhinos that can be hunted. These are animals that are old, no longer capable of breeding and are considered a dangerous threat to other younger animals.
He said the threat to the rhino is from its own kind. "One of the other ear-tagged killer rhinos is going to injure it. And then either lions or hyenas are going to drag it down. It's going to die [in] a horrible manner, slowly."
So Knowlton argues, why not let a hunter pay a massive amount of money to take out a threat to the rest of the species. The Dallas Safari Club says the $350,000 paid by Knowlton will be donated to the Namibian government's black rhino conservation efforts."
