Marine debris entanglement kills hundreds of thousands of marine animals annually. Understanding the scale and solutions helps direct welfare action effectively.
Marine debris entanglement is a welfare crisis of enormous scale. Animals caught in ghost nets experience prolonged suffering: constriction injuries as they grow around netting, inability to feed, exhaustion from attempts to escape, and ultimately drowning or death from secondary infection. Seals with plastic rings around their necks suffer progressive strangling as they grow. Each of these is an individual welfare catastrophe. Prevention (reducing fishing gear loss, banning single-use plastics, developing biodegradable gear) is the highest-leverage intervention. Emergency response organisations like BDMLR provide rapid rescue and release of entangled animals in UK waters, with significant welfare benefits for survivors.
