BP Oil Spill May Have Contributed to Dolphin Deaths
The 2010 BP oil spill contributed to an unusually high death rate for dolphins in the Gulf of Mexico, a new study suggests.
Between January and April 2011, 186 dead bottlenose dolphins washed ashore between Louisiana and western Florida. Most alarmingly, nearly half of these casualties were calves, which is more than double the usual proportion of young to old dolphins found dead. Scientists now blame both natural factors and human catastrophe for the unusual die-off.
