People then decide to volunteer with good intentions of making a difference, spending anywhere from a few weeks to several months at an African game range or reserve to contribute to the further survival of many different majestic animals. Unfortunately, some volunteers don't realize that they are doing the exact opposite. Too often they become part of an organization that actually contributes directly or indirectly to the killing of the exact animals, they thought they were protecting.
The majority of people have now realized that there is an actual industry for wealthy people, who pay large sums of money to travel to African countries with the sole purpose of hunting animals, to leave with a trophy for their wall at home. While this is legal in some countries like South Africa, this demand for trophy hunting has across Africa led to another business also known as "canned hunting."
Canned hunting is the practice of keeping exotic animals in captivity for their entire lives. It's a practice which has become popular with big cats, in particular lions. When they are cubs, the owners make profit on tourists coming to pet and cuddle them. Of course, who doesn't think that a lion cub is the most adorable thing? However, when these same lions become too big to be wanted for petting, they are locked up with a large number of other young male lions in cages.
Here they wait for the one day when a wealthy trophy hunter comes along paying a large sum of money. When this happens, a lion is "released" into an enclosed area with the hunter, so he/she can "hunt" his/her new trophy. It is estimated that there's only around 30,000 wild lions left in Africa, yet of the 10,000 lions left in South Africa, only around 3,000 of them are actually wild. Meaning that the vast majority of lions actually are captive.
