South Africa has the biggest captive big cat industry in the world and it is largely unregulated.
While the international conservation community unites against the captive breeding of big cats in South Africa, the government stalls.
Captive breeding takes place in South Africa and no other country is permitted to export lion bones.
A stronger ban on lion trade by CITES would have helped to lessen some of the threats lions face but it would have not have protected the animals from sport hunting.
Making tiger trade illegal has had unintended consequences on lions. The problem has escalated over the last few years.
