were hunted heavily, almost to the point of extinction. Only their willingness to breed in captivity and the inhospitability of their mountainous habitat prevented this. Despite these factors, the markhor is still endangered. American bison The American bison is a large bovid which inhabited much of western North America prior to the 1800s, living on the prairies in large herds. However, the vast herds of bison attracted market hunters, who killed dozens of bison for their hides only, leaving the rest to rot. Thousands of these hunters quickly eliminated the bison herds, bringing the population from several million in the early 1800s to a few hundred by the 1880s. Conservation efforts have allowed the population to increase, but the bison remains near-threatened due to lack of habitat. White rhino The Journal of International Wildlife Law and Policy cites that the legalization of white rhinoceros hunting in South Africa motivated private landowners to reintroduce the species onto their lands. As a result, the country saw an increase in white rhinos from fewer than one hundred individuals to more than 11,000, even while a limited number were killed as trophies. However, the illegal hunting of rhinoceros for their horns is highly damaging to the population and is currently growing globally, with 1004 being killed in South Africa alone according to the most recent estimate. The White Rhino (along with the other 4 rhino species) are poached due to beliefs that the Rhinos horns can be used to cure Cancer, Arthritis and other diseases and illnesses, even though they are scientifically proven wrong. Other species According to Richard Conniff, Namibia is home to 1,750 of the roughly 5,000 black rhinos surviving in the wild because it allows trophy hunting of various species. Namibia's mountain zebra population has increased to 27,000 from 1,000 in 1982. Elephants, which "are gunned down elsewhere for their ivory", have gone to 20,000 from 15,000 in 1995. Lions, which were on the brink of extinction "from Senegal to Kenya", are increasing in Namibia. In contrast, Botswana in 2012 banned trophy hunting following a precipitous wildlife decline. The numbers of antelope plummeted across Botswana, with a resultant decline in predator numbers, while elephant numbers remained stable and hippopotamus numbers rose. According to the government of Botswana, trophy hunting is at least partly to blame for this, but many other factors, such as poaching, drought and habitat loss are also to
