Threats to wildlife species, their habitats and natural ecosystems in general arise from a variety of sources. Various species have been captured through the centuries for food. Exploitation has taken numerous forms, such as hunting for skins, feathers, and other products used or traded by mankind; capturing for display in zoos, for scientific research, keeping as pets, and for medicinal, cultural, religious and artistic purposes, amongst others. However, it is now apparent that the conservation of living resources cannot be achieved merely by controlling the means for their exploitation by humankind. In particular, wild plants and animals cannot be conserved simply by focusing on the protection of individual species through controls over human activities impinging directly upon such species. Their protection also requires the preservation of their habitat and the complementary protection of related and dependent species, as well as the non-living elements of the environment on which they all rely (Birnie and Boyle, 2002: 4).
