Marine debris refers to any human-made material that ends up in oceans, rivers, and other waterways. This can include items like plastic bottles, fishing nets, and metal scraps. Marine debris can harm wildlife, as animals may ingest or become entangled in these materials. The presence of marine debris poses significant environmental challenges. It can disrupt ecosystems and damage habitats, such as coral reefs and beaches. Efforts to reduce marine debris often focus on recycling, waste management, and community clean-up initiatives to protect marine life and maintain clean waterways.
