@foe_us: Deepwater Horizon was the largest marine oil spill in the history of the petroleum industry, dumping 210 million gallons of oil into the Gulf of Mexico. @UC San Diego’s Scripps Institution of Oceanography have been analyzing the echolocation clicks and communication signals of marine animals from the Gulf – and found a strong correlation between this oil spill in steep declines in local whale and dolphin populations. This is the cost of Big Oil. #oil #fossilfuels #whales #ucsd #oceans
