WASHINGTON (CBS DC) – The U.S. Navy acknowledged Friday that hundreds of marine mammals will die during bomb testing and heavy sonar use.
The Navy determined that over 340 dolphins and whales will die between 2014 to 2019 as a result of these training procedures.
The bombs that the Navy will be detonating off of the East and West Coasts and the Gulf of Mexico will cause most of the dolphin and whale deaths. The Navy added that “behavioral changes” could also occur from active sonar use.
Sonar use is theorized to affect mammals because they use echolocation to find food and navigation. In a number of cases it’s been fatal for these animals such as dolphins.
The Navy insists that this training is essential to national security and it can’t be simulated through a computer.
