"Anti-poaching 'war' to save rhinos whose horns are more valuable than gold" - Addison Norman

For years wildlife advocates have been in battle against rhino poachers. Rhino horn can sell for $5,550 an ounce mostly to asian countries where rhino horns in a sign of wealth and believed to be a panacea against sickness. The animal is already dwindling in population and may reach extinction if poaching for rhino horns doesn't stop. In response to the killings, The Wildlife Veterinary Team has recently started conducting experiments on the rhinos in Kruger Nation Park in South Africa that has already had 1,020 rhinos poached this year. In the experiment veterinarians take DNA samples as well as a tracking devices in hopes of catching poaching groups in the area. The national park shares a 350 km border with Mozambique, and officials believe most poachers come from this unprotected border. Now park rangers are more of a military security force than rangers. 

When the U.S. began to acquire more territory more people moved west. A problem included the conflict with preexisting native american tribes in the areas. To try to push the indians from their lands government officials killed native americans main food source, the buffalo. Some governments in the U.S. would pay money to each person who killed a buffalo. Just as rhinos are killed for their horn, American bison were massacred for money and to push people from their home.
