Have these ecosystems and the affected populations full recovered from this oil spill

The Deepwater Horizon oil spill happened in 2010 and is known as the worst oil spill that has ever happened in the Gulf of Mexico. In this event, 5 million barrels of oil were poured into the sea, which resulted in the death of 7 workers, in addition to the destruction of much of the local ecosystem.

This spill lasted 87 days and spread for about 1500 km in the Gulf of Mexico, contaminating the water and killing thousands of animals. Although a team from Deepwater Horizon carried out a cleaning of the site, there are still traces of the leaked oil, which indicates that the ecosystem has not fully recovered. In addition, researchers were able to find petroleum compounds in many animals in the region and even in bird eggs.
