Human-made noise pollution in the Earth's oceans and seas is becoming a serious threat to sea wildlife. Scientists report that there is hardly an underwater place left where sea mammals can live in peace and quiet. Dozens of species of whales, dolphins, turtles and other creatures depend on sound in their communication, finding mates and hunting for food. So noisy environment is making it difficult to lead a normal life. This is according to a report from the International Fund for Animal Welfare (IFAW), called «Ocean Noise: Turn it Down». The environmental group says noise from shipping, oil and gas surveys, offshore construction and water sports has reached dangerous levels for sea life The IFAW says the distance over which blue whales can communicate is down by 90 per cent. It also reports that in the past decade, many whales have become beached after being disorientated because of loud noise. The group also warns that noise pollution is only going to get worse. There are 90 survey ships active in the oceans today. In addition, the number of ships sailing the seas will double by 2025. Mark Simmonds, a lFAW spokesman, said « man-made noise is already causing a kind of acoustic fogy, and called for a «response to noise pollution in the underwater».
