The entire world is celebrating World Environment Day this year on June 5th. The day was chosen by the United Nations to honor the 1972 UN Conference on the Human Environment.

Every year, a different city or region hosts the World Environment Day with a different theme. In 2010, Kigali, Rwanda hosted World Environment Day and promoted the theme “Many Species. One Planet. One Future.” In 2007, the event was hosted by Tromso, Norway with the theme “Melting Ice – A Hot Topic?”

This year, the host is the island nation of Kiribati and the theme is “Raise Your Voice, Not the Sea Level.”
