World Environment Day
The United Nations designated 5 June as World Environment Day to highlight that the protection and health of the environment is a major issue, which affects the well-being of peoples and economic development throughout the world. The celebration of this day provides us with an opportunity to broaden the basis for an enlightened opinion and responsible conduct by individuals, enterprises and communities in preserving and enhancing the environment.
The theme of the 2024 World Environment Day is “land restoration, desertification, and drought resilience.”

As we mark World Environment Day and World Day to Combat Desertification and Drought, UNESCO is calling for a renewed commitment to life in all its forms. Our Organization's commitment can be summed up in three verbs: alert, promote and restore.
