The celebration of World Environment Day began in 1972, being celebrated every year on June 5th. It is an annual event that aims to highlight positive actions for the protection and preservation of the environment and to alert populations and governments to the need to save the environment. Every year, the United Nations presents a theme, which serves as a starting point for the development of actions to celebrate World Environment Day in more than 100 countries, with various activities programmed according to this theme. The events aim to present new ways and methods to preserve the future of humanity, whether through individual citizen or collective actions.
