NBC News has an update on the spill.
Even if the [wildlife] death toll is relatively low, the impact to area marine mammals, such as dolphins and sea otters, could take years before it's fully understood, said Michael Jasny, of the Natural Resources Defense Council, an environmental advocacy group.
A new study published [last] Wednesday in the scientific journal PLOS ONE found that the record dolphin die-off now occurring in the Gulf of Mexico is linked to contaminants in the water from the Deepwater Horizon spill.
Dolphins don't avoid the oil sheens, which means they're "inhaling the fumes that could very well cause disease," said Jasny, the NRDC's director of its marine mammal protection project.
"The oceans are so opaque to us," he added, "and the harms we inflict in it are often invisible."
