The slaughter of rhinoceros

I've written five posts about the ongoing worldwide slaughter of rhinoceros.  I hate to keep harping on the subject, but it keeps happening:

Nearly 700 rhinos have been killed in South Africa in 2013, making it the bloodiest year yet for rhino poaching. Last year, a record 668 rhinos were poached for their horns, but that figure has already been eclipsed with the deaths of 688 rhinos with three months left of the year, figures from the South African government show. There are around 18,000 white and 4,000 black rhinos in the country.

The dramatic growth in rhino poaching in South Africa, up from just 13 in 2007, has largely been driven by demand in Asia, in particular Vietnam, where rhino horn is seen as a status symbol. A survey of 720 people in Hanoi and Ho Chi Minh City, published earlier this month, found that typical buyers were "educated, successful and powerful individuals" and use rhino horn as currency in networking.
