World Environment Day, is the UN's biggest global celebration for positive environmental action. The 2010 theme focuses on the central importance to humanity of the globe's wealth of species and ecosystems, in support of the 2010 UN International Year of Biodiversity.

This year's host country, Rwanda, was chosen for its combination of environmental richness, including rare species such as the mountain gorilla, allied to pioneering green policies. Millions of people on every continent will take action for the planet under the theme, Many Species. One Planet. One Future.

Celebrations in Europe include major public events in Geneva (Switzerland), Baku (Azerbaijan), and Genoa (Italy), alongside a multitude of events across the continent - among them a circus and poetry slam in Eskilstuna (Sweden), and the screening of a series of environmental films entitled 'Télégrammes Visuels' in Paris (France). Italy's top environmental film festival, Cinemambiente in Turin, will also feature more than 30 documentaries and short films on the environment.
