In Colombia, in South America, the biggest drain on some wildlife species is the international pet trade. For every quetzal or cock-of-the-rock that reaches its destination alive, fifty die, and whole populations are being exterminated, says Dr. Lehmann, who is Director General of the Valle State Museum of Natural History. The skin trade, urged on by the need for foreign exchange, is another serious drain. National Parks are the only hope in Colombia as elsewhere, but the importing countries, such as the USA and these of western Europe, could do much to reduce the trade in both pets and skins.
