World Wildlife Day is observed annually on 3rd March. It was established by the United Nations General Assembly (UNGA) in 2013 to raise awareness about the world’s wild fauna and flora and to promote conservation efforts.
Detailed Explanation:
The date 3rd March was chosen because it coincides with the adoption of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1973.
The day highlights the importance of protecting wildlife and their habitats, addressing threats such as illegal wildlife trade, habitat destruction, and climate change.
