The document discusses coastal pollution in Sri Lanka. It aims to define coastal zones, explain their importance, define coastal pollution, identify sources of pollution, and discuss ways to prevent it. The coastal zone is where land meets sea. Major sources of coastal pollution include marine commerce, industry, sewage treatment, and recreation. Impacts include destroyed coastal ecosystems, effects on tourism and fisheries, and health problems. While efforts have been made to protect coastal zones, more work is needed to fully address this issue.
