It began on the 20th of April 2010, in the gulf of Mexico
A explosion occured on an oil rig that was getting oil, and it was so deep down in the ocean that they couldn't fix it and the oil just came gushing out.
More than 8000 birds, sea turtles and marine mammals where found dead or injured 6 months after the oil spill.
Animals weren't the only things that got effected by the oil spill, humans also got effected
Oil contains petroleum hydrocarbons witch are toxic and irritating to the human skin, also the oil had a horrible smell that made people vomit and have headaches.
