The majority of species in the exotic pet trade are not protected by international agreements, and so there is no limit on how many individuals can be removed from their natural habitat. Even where limits are set, they are often ignored. As a result, wild animal populations that were once healthy can quickly become endangered.
Scientists have learned to be deliberately vague about the whereabouts of newly discovered species, as they are likely to be quickly tracked down by wildlife dealers. The pet industry is so out of control that numerous species previously unknown to science have even been discovered, not in their natural habitat, but in the pet trade!
