Whales and Dolphins Can No Longer Hear in Oceans
The International Fund for Animal Welfare (IFAW), just released a report showing that in recent decades, the noise created in the ocean by human activities has risen significantly, which poses a major threat to marine mammals.
Commercial shipping noise, seismic exploration, sonar, and off-shore construction and recreational activities are all contributing to an increasingly more disorientating environment for mammals in the ocean.
Under-water sounds for communication, navigation and food locating are key for whales, dolphins, porpoises and other cetaceans. Man-made noise pollution can cause behavioral changes such as abandoning breeding and feeding areas, and in some cases lead to mass stranding and even death.
“Protecting marine species from ocean noise is critical to their survival. Ocean noise can travel over vast distances and affect marine species across many national sea boundaries. Therefore it is vital that countries work together to build strong agreements to prevent marine species being drowned out by disruptive, man-made noise.” - Veronica Frank, IFAW Campaign Officer
