The invisibility of noise pollution: one of the biggest pollution problems of the 21st century. To this day, humans continue to be unaware of the sounds that occur in the sea. We are also the main cause of anthropogenic noise. One of the main causes of this pollution is maritime traffic. This increase in noise pollution is causing chronic effects that can affect the long-term ability of animals to carry out their normal activities, such as reproduction. In addition, this prevents communication between marine specimens, such as whales.
