action for the protection of the environment. It is supported by many non-governmental
organizations, businesses, government entities, and represents the primary United
Nations outreach day supporting the environment.
First held in 1973, it has been a platform for raising awareness on environmental issues as marine
pollution, overpopulation, global warming, sustainable development and wildlife crime.World
Environment Day is a global platform for public outreach, with participation from over 143
countries annually. Each year, the program has provided a theme and forum for businesses, non
government organizations, communities, governments and celebrities to advocate environmental
causes
World Environment Day was established in 1972 by the United Nations at the Stockholm
Conference on the Human Environment (5–16 June 1972), that had resulted from discussions on
the integration of human interactions and the environment. One year later, in 1973 the first WED
was held with the theme "Only One Earth".
