Plastic pollution devastates oceans, harming marine life and ecosystems. Discarded plastics persist for centuries, leaching toxins and disrupting food chains. Marine animals often ingest or become entangled in plastic debris, leading to injury or death. Microplastics, smaller particles, infiltrate the food web, potentially affecting human health. Plastic pollution also damages coastal economies, impacting tourism and fisheries. Mitigation efforts, including reduced plastic use and improved waste management, are crucial to safeguarding marine environments and the millions who depend on them.
