The United Nations Conference on the Human Environment aka the Stockholm conference held in 1972 became the first global conference with the environment as its main agenda and it declared the right to live in a healthy environment as a basic human right . Not only was the idea of a World Environment Day formalized there, but also this conference saw the creation of the United Nations Environment Programme.
World Environment Day, over the years, has become a global platform for people from all walks of life to participate in various environmental protection awareness campaigns. The celebration of World Environment Day is done each year according to a specific theme and slogan that respond to the major environmental concern of the time. It is hosted by a different country each year.
For example, India hosted the 45th World Environment Day celebration under the theme “Beat Plastic Pollution”. The celebration of World Environment Day last year also launched the United Nations Decade of Ecosystem Restoration (2021-2030), which is a global mission to revive billions of hectares, of forests to agricultural land, from the top of the mountains to the bottom of the sea.
