On December 20, 2013, the United Nations General Assembly, by its resolution (A / RES / 68/205), decided to declare March 3 as World Wildlife Day, with the aim of raising the awareness of the general public on wildlife and flora issues. This event was a separate milestone in the history of the UN, which made this decision.

In the same year, it was noted 40 years since the adoption of another important document in the field of protecting natural diversity. It was called the Convention on the International Trade in Endangered Species of Wild Fauna and Flora. The birthday of the document was March 3, 1973.

The birth of the holiday in the UN was preceded by the initiative of the participants of the Conference of the Parties to CITES, held in Thailand in spring 2013. It is necessary to clarify that this meeting is held between representatives of the countries that signed the Convention of March 3, 1973. It was at this Conference that it was proposed to declare March 3 as World Wildlife Day. With this proposal, the participants of the Conference appealed to the United Nations, presenting there the results of the Conference itself.
