Windhoek (AFP) - A US hunter who paid $350,000 to kill a black rhinoceros in Namibia successfully shot the animal on Monday, saying that his actions would help protect the critically-endangered species. Corey Knowlton, from Texas, downed the rhino with a high-powered rifle after a three-day hunt through the bush with government officials on hand to ensure he killed the correct animal. Knowlton, 36, won the right to shoot the rhino at an auction in Dallas in early 2014 -- attracting fierce criticism from many conservationists and even some death threats. He took a CNN camera crew on the hunt to try to show why he believed the killing was justified. "The whole world knows about this hunt and I think it's extremely important that people know it's going down the right way, in the most scientific way that it can possibly happen," Knowlton told the TV channel in footage released Wednesday. "I think people have a problem just with the fact that I like to hunt... I want to see the black rhino as abundant as it can be. I believe in the survival of the species." "I felt like from day one it was something benefiting the black rhino," Knowlton said just after the hunt ended, his voice croaking with emotion. So basically an old Black Rhino charges after the young endangered species and it can kill calves, cows, etc. OK , I'll buy that. SO WHY NOT use the $350,000 to capture it and put it in a zoo where it can be taken care of?? No, you have to kill it to save the species. Give me a freaking break!!! All BS in my opinion. He probably could've paid $100,000 or way less to capture it and give it a home in a zoo.
