Deepwater Horizon, Nine Years Later

It has been nine years since the Deepwater Horizon disaster and the effects of the consequent oil spill are still felt today. On the 20^th of April 2010, the oil drilling rig Deepwater Horizon exploded resulting in the death of 11 people. Then only two days later, the rig sank which led to five million barrels of oil being spilt into the Gulf of Mexico over a three-month period. It is the worst spill in US history and one of the catalysts behind the climate change movement.  What have we learned from it?
