A new report warns that levels of noise in the world's oceans are causing serious problems for whales, dolphins and other marine mammals. Undersea noise blocks animals' communication and disrupts feeding, according to the International Fund for Animal Welfare (Ifaw). Some say naval sonar has been linked to the mass deaths of some cetaceans. The level of ocean noise in some regions is doubling each decade and Ifaw says protective measures are failing. "Humanity is literally drowning out marine...
