The Deepwater Horizon oil spill has caused 172 million gallons of oil to leak into the Gulf of Mexico and massive amounts to come ashore, destroying wetlands and marshes in southern Louisiana, Alabama and Florida. The marshes serve as the critical nursery grounds for wildlife, providing many species that are unique to Louisiana with the ideal conditions for breeding and growth.

Scientists say that they will not be able to see the effect of the oil spill on marine life until larger contaminated microorganisms make their way up the food chain. In other words, the shrimp eats the contaminated plankton. The fish then eats the shrimp and then gets eaten by large mammals. Then scientists start to see the effect that the oil has on the wildlife living along the gulf coast.
