Although the Navy agreed to limit its use of low-frequency sonar, it continues to blast the world's oceans with mid-frequency sonar, which can be just as harmful to whales and other marine mammals. Tell the Navy to turn off the noise.

I pledge to go to http://www.nrdconline.org/campaign/nrdcaction_092506_a and send the NRDC's letter to US Navy Secretary Donald Winter asking for a limitation tof the use of such sonar.
