Scientists have discovered a unique oil-eating bacteria in the Mariana Trench, the deepest part of the Earth's oceans. It may pave the way for sustainable ways to clean up oils spills. The Mariana Trench is located in the Western Pacific Ocean and reaches a depth of 11,000 meters. By comparison, Mount Everest is 8,848 meters high. To date, only a few expeditions have investigated the organisms inhabiting this ecosystem.
