Save Whales, Seals and Dolphins From Deadly Sonar
5 years ago

Whales and other marine mammals already struggling for survival desperately need your help. Newly proposed rules would allow the Navy to harm or harass marine mammals, including endangered species like Hawaiian monk seals, more than 30 million times during its training exercises off the Atlantic, Hawaiian and Southern Californian coasts over the next five years.

The Navy uses underwater detonations, sinking of ships, gunnery exercises and active sonar so loud and intense that it can seriously harm or kill marine mammals.

Whales and other marine mammals use sound for communication, locating food and reproduction. Sonar interferes with these basic functions and can also injure and kill the animals. The Navy's mid-frequency sonar has previously resulted in mass strandings of marine mammals in the Bahamas, Puget Sound and Hanalei Bay, Hawaii.

The effects of sonar on these animals aren't pretty. Exposure to sonar can lead to trauma, bleeding around the brain and ears, and the formation of large bubbles in the animals' organs.
