In case you haven't heard, the Navy wants a sonar testing area along NC's coast. They say no effect on marine life. Opponents say big effect on marine life.
Some people blame various instances in the past of beached whales (and other marine life) on sonar testing. I remember a Big Rock tournament not too long ago that coincided with sonar testing, which was blamed by some fisherman for the slow bite.
I don't think anyone is against the Navy or its' intentions. But there appears to be a
possibility of negative impact on our fishing and associated economy.
