World Oceans Day clouded by oil spill

Conservation groups, schools, businesses and governments across the globe are planning events and activities Tuesday to celebrate the world’s oceans, a day of tribute tinged by worry over the impact of a devastating oil spill in the Gulf of Mexico.

The United Nations recognizes June 8 as World Oceans Day. The “holiday” was officially celebrated for the first time last year, though the concept of a day to pay homage to the world’s oceans was first proposed in 1992 by Canada at the Earth Summit in Rio de Janeiro.
