Stop killing dolphins with sonar testing

Military sonar testing uses destructive sound frequencies that affect all sea animals that navigate by sonar.

there are many unexplained incidents of dolphin pods beaching themselves suicidally for no known reason, and often there is sonar testing going on.

there are increasing numbers of whales going aground or going into shallow waters. 

The MOD are testing sound as a weapon, so it is certain to be painful and destructive to these animals. There must be a different way to do this, sonar testing must stop.
