The Convention on International Trade in Endangered Species of Wild Fauna and Flora, commonly known as CITES, is an international agreement aimed at ensuring that international trade does not threaten the survival of wild animals and plants. Established in 1973, it provides a framework for countries to regulate and monitor the trade of endangered species through a system of permits and quotas. CITES classifies species into three categories based on their level of protection needed: Appendix I includes species threatened with extinction, Appendix II includes species that may become endangered if trade is not regulated, and Appendix III includes species protected in at least one country. By working together, countries aim to conserve biodiversity and promote sustainable use of natural resources.
