Three years after the massive oil disaster in 2010, and the Gulf of Mexico is still a very, very ill ecosystem according to a new study.

The National Wildlife Federation is pointing to the continuing deaths of Dolphins, which are at the top of the Gulf food chain: "A strong indication that there is something amiss with the Gulf ecosystem," says Federation senior scientist Doug Inkley.

Turtles are also in poor shape, although the US Government claims the fishing nets are causing the Turtle deaths and a bacterial infection is getting the Dolphins.

"Both species have very high mortality the first year, slightly lower the second year and the third year even lower, but still well above average," Inkley added, "To have these deaths above average for so long a period of time is unprecedented."

The federation's report, "Restoring a Degraded Gulf of Mexico: Wildlife and Wetlands Three Years into the Gulf Oil Disaster," rated the status of coastal wetlands, Atlantic bluefin tuna, and sea turtles as poor; bottlenose dolphins and deep-sea coral as fair; and shrimp and brown pelicans as good.
