text: Kangaroos Kangaroos are currently legally harvested for commercial trade and export in Australia. There are a number of species included in the trade including:
  Red kangaroo (Macropus rufus)
  Eastern grey kangaroo (M. giganteus)
  Western grey kangaroo (M.fuliginosus)
  Common wallaroo (M. robustus)
  Harvesting of kangaroos for legal trade does not occur in National Parks and is determined by quotas set by state government departments.  Active kangaroo management has gained a commercial value in the trade of kangaroo meat, hides and other products.
  North America
  Alligator
  Alligators have been traded commercially in Florida and other American states as part of a management program. The use of legal trade and quotas have allowed management of a species as well as economic incentive for sustaining habitat with greater ecological benefits.
  Legalising trade for endangered species
  Legalising the trade of products derived from endangered species is highly controversial. Many researchers have proposed that a well regulated legal market could benefit some endangered species by either flooding the market with products that drive down the price of illegal products, decreasing the incentive to illegally harvest, or by providing revenue that could fund the species's conservation. However, laundering and corruption pose a major obstacle to implementing such policies, as illegal harvesters attempt to disguise illegal product as legal when trade is legalized.
