Marine pollution from plastics, chemicals, and noise causes significant welfare impacts on fish and other marine animals. Understanding these impacts is essential for driving meaningful policy change.
Fish are sentient animals capable of experiencing pain and stress, yet their welfare in marine environments is rarely considered in pollution policy discussions. Plastic ingestion causes internal injuries and blockages. Chemical contamination impairs neurological function, potentially reducing the ability to perceive and respond to stimuli normally - including pain signals. Noise pollution causes acute stress responses and chronic physiological strain. Entanglement in fishing gear causes prolonged, terrifying suffering before death. The sheer scale of these welfare harms - affecting billions of individual fish - makes marine pollution one of the most significant animal welfare issues of our time.
