Bulgaria will join world celebrations of the Environment Day - June 5.
Special ecological games for endangered species will be held in Sofia for the children.
The United Nations Environment Programme (UNEP) announced that the World Environment Day theme is " Don't Desert Drylands!"
The celebration reminds us of the importance of caring for the world's vast areas of arid and semi-arid land. This year the celebration will be held for the first time in Algiers.
The UN General Assembly has designated the year 2006 the International Year of Deserts and Desertification. In keeping with tradition, UNEP has chosen the theme to coincide with the International Year to highlight this pressing environmental issue.
