So, as most of us should know, one of the most disastrous oil spills of the century happened a few months ago of the gulf of Mexico. In July, BP was able to cap the well that was spewing out tonnes of oil. However, there still remains the after-effects of the spill and how the oil is going to be cleaned up.
As a result, BP decided to use massive amounts of chemical dispersants deep underwater to break up the oil before it reached the surface.
It was to make it easier for oil-eating microbes to do their eat up the oil. But the risk was that the microbes would use up the oxygen in the water and cause a dead zone, which was a place where fish could not survive.
Luckily, the oil-eating microbes did not take up too much oxygen and create a dead zone. One reason that oxygen levels didn't drop too low was the natural mixing of water in the Gulf, which kept bringing in oxygen from other areas
There has also been the problem of whether the dipersants would have any long term effect on marine life and its toxicity.
In conclusion, I hope that BP could clean up the oil spill quickly and let the coastal communities and animals return back to their normal lives.
