My OperaBlue whale and Noise pollution

Besides being threatened by enviromental pollution caused by waste and oil leak, the blue whale is now facing another dangerous kind of pollution, noise pollution. In recent years the increasing use of hi-tech sonar by ships, the noise of propellers, seismic surveys, sea-floor drilling, and low-frequency radio transmissions have made oceans noisier. The growing "acoustic smog" in the world’s oceans, and particularly the waters near popular migration and feeding routes, is interfering with whales’ ability to communicate with songs. Deadly military solar spreads through the oceans, drastically cutting down their ability to communicate, impeding the beasts' ability to navigate and find mates. For example, US Navy, backed-up by a set of eleventh-hour rules, is using sonar during training exercises in all oceans, splitting the whale’s ear. This activity affects tremendously to the whale’s population as whales use their songs to find their mates, if females can no longer hear the singing males through the smog, they lose breeding opportunities and choices.
