CITES

CITES, which stands for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, is a global agreement among governments to regulate or ban international trade in species under threat. 

In the mid-20th century, governments were beginning to recognize that trade in some wild animals and plants had a devastating impact on those species. These species were being driven toward extinction through unsustainable use for food, fuel, medicine, and other purposes.

And while individual governments could control what happened within their borders, they did not have a way to address the impacts of international trade in these species. In 1973, 21 countries addressed this issue by signing the CITES agreement.
