World Wildlife Day is observed on March 3 to raise awareness about conserving wild animals and plants. It was proclaimed by the United Nations General Assembly in 2013, and the date marks the signing of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1973. The theme for 2026 is 'Medicinal and Aromatic Plants: Conserving Health, Heritage and Livelihoods.'
