Description

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. Two years later, in 1974 the first WED was held with the theme "Only One Earth". Even though WED celebrations have been held annually since 1974, in 1987 the idea for rotating the center of these activities through selecting different host countries began.
