SPAIN Illas Ons -- 15/12/2002 -- Aerial view of Ons Island in the Atlantic Islands National Park off the Galician coast which has been severly affected by oil pollution. Several thousand tonnes of heavy fuel oil has contaminated large swathes of the north-western coast of Spain after the tanker Prestige sank in late November 2002. The ship was carrying around 77,000 tonnes of fuel oil and while some has been extracted from the wreck, a lot of the oil has leaked into the sea causing a ecological disaster along much of the southern Atlantic coast of Europe
