An Iranian oil tanker, carrying approximately 1 million barrels of oil, collided with a cargo ship in the East China sea. The tanker had been engulfed in flames, releasing 1000 meter high plumes of black smoke, for eight continuous days, before finally sinking on Sunday 14th January. Although Greenpeace expect that most of the oil will burn of rather than enter the water, there is still a significant potential of a serious impact on marine life and ecosystems. The ship, which was carrying 136,000 tonnes of light crude oil, is toxic and more explosive than than regular crude oil. Click here for more information.
