It is my opinion that certain factions in the Navy do not like whales and dolphins because these very intelligent cetaceans see all that is going on in the seas. Some of these beings stick their noses into what the Navy is doing underwater and the Navy retaliates with sonar. I don’t think it is happenstance that cetaceans are driven onto beaches and die because of the damage caused to them by sonar. That is my opinion on the matter.
The Navy is being sued in an attempt to protect marine mammals from the use of sonar. Good luck!
