Is sonar harmful?

Answer:

Sonar has been linked to injury and to the stranding of whales and some other marine mammals. It is difficult to actually prove a "causal connection" between sonar and the injuries and strandings, but oceanographers and marine biologists are working on this issue. Laws have been passed recently in the U.S. and the military has been given a Presidential override on their use of sonar because it is too important to national security to restrict its use.
