Re "Sonar testing plans raise concern" (Capitol & California, Dec. 16): Our marine life appears to be under attack. We had detected oxygen-deprived ocean areas, also known as "dead zones," off the coasts of California and Oregon. We have collapsing fisheries, acidification of the oceans because of global warming and nuclear debris contamination. And now this: The U.S. Navy has been granted permission to begin sonar and explosive testing off the coast of California and near Hawaii. It is appalling that the National Oceanic and Atmospheric Administration has authorized these plans. The evidence is clear: Mass marine mammal strandings have increased since the military began sonar use and testing explosives. Now, blue whales have been observed having detrimental effects due to sonar exposure. The Navy admits the testing could kill as many as 186 whales and dolphins off the East Coast and another 155 off Hawaii and Southern California. Do we really want our tax dollars spent this way? I'm not convinced this activity is in the best interest of our national security.
