Every year, more than 12 million tons of oil get dumped into the world’s oceans. It happens due to the leakage of oil from damaged wells and tankers. About 25% of seawater is covered with a layer of oil varying in thickness. In 2010, an explosion of The Deepwater Horizon oil platform resulted in the leakage of 1000 tons of oil into the ocean. The British Petroleum company has spent billions of dollars to eliminate the substance but despite all efforts, they could only remove 75% of the combustible substance.
260 million tons of plastic debris get into the ocean annually, resulting in the formation of huge plastic continents. The biggest one is located in the Pacific Ocean taking up 10% of its surface.
