Noise of human activities is impacting marine life, according to a new study by researchers from the University of Exeter.
The loud cacophony of noise is as harmful as overfishing, water pollution and the climate crisis but is often overlooked.
While these other issues have lingering effects, noise can be stopped instantly.
Sealife often use sound to detect pray, defend their territory and navigate but noise pollution could make this difficult.
The study described noise pollution as an 'acoustic fog' in the ocean.
