The mass murder of Navy sonar

I don't think the US Navy would get away with deploying technology that visibly tortured and killed large numbers of land mammals ...

Does Military Sonar Kill Marine Wildlife?: Scientific American:

... generate slow-rolling sound waves topping out at around 235 decibels; the world’s loudest rock bands top out at only 130. These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source...

... Navy documents which estimated that such testing would kill some 170,000 marine mammals and cause permanent injury to more than 500 whales, not to mention temporary deafness for at least 8,000 others...

Imagine the pain of being unable to escape this barrage.
