A lot of debate among conservationists centers on the conflict between the desire to see a species totally protected from human exploitation and the reality that market forces will continue to exist (see the latest on shark fin bans for a very good example). Ideally, a conservation plan should strike a balance, ensuring the continued existence of the species while still allowing people to profit from it in some way. This also requires a clear idea of the limitations of conservation policies. For example, US policies (even the mighty Endangered Species Act) only directly affect populations within the territorial waters of the United States, while international agreements like CITES restrict trade of the species without telling any particular country what to do domestically. However, there are ways to track the interaction between conservation policies and the market, making it possible to make some predictions on how things like fishery management plans and CITES listings might affect trade. Then it gets interesting. Armed with this knowledge, can the market be pushed towards species conservation?
