Wildlife trade refers to the products that are derived from non-domesticated animals or plants usually extracted from their natural environment or raised under controlled conditions. It can involve the trade of living or dead individuals, tissues such as skins, bones or meat, or other products. Legal wildlife trade is regulated by the United Nations' Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which currently has 184 member countries called Parties. Illegal wildlife trade is widespread and constitutes one of the major illegal economic activities, comparable to the traffic of drugs and weapons. Wildlife trade is a serious conservation problem, has a negative effect on the viability of many wildlife populations and is one of the major threats to the survival of vertebrate species. The illegal wildlife trade has been linked to the emergence and spread of new infectious diseases in humans, including emergent viruses. Global initiative like the United Nations Sustainable Development Goal 15 have a target to end the illegal supply of wildlife. Terminology Wildlife use is a general term for all uses of wildlife products, including ritual or religious uses, consumption of bushmeat and different forms of trade. Wildlife use is usually linked to hunting or poaching. Wildlife trade can be differentiated in legal and illegal trade, and both can have domestic (local or national) or international markets, but they might be often related with each other. Ineffective monitoring of international wildlife trade The volume of international trade in wildlife commodities is immense and continues to rise. According to an analysis to the 2012 Harmonized System customs statistics, global import of wildlife products amounted to US$187 billion, of which fisheries commodities accounted for $113 billion; plants and forestry products for $71 billion; non-fishery animal for $3 billion including live animals, parts and derivatives. However, the global trade of wildlife commodities is ineffectively monitored and accounted for due to the constraint of the HS Code System used by the customs worldwide. The majority of international imports of wildlife are only recorded in extremely basic and general categories, such as 'plant' or 'animal products', with no further taxonomic detail. It is estimated that near 50% of the global import of plant and 70% of animal products are imported as general categories, with an exception for fisheries (ca. 5%), thanks to various multilateral fishery management agreements that requires taxon-specific fish catch reporting.
