Marine pollution stems from various sources like agriculture, industry, and shipping. It includes chemical, physical, and biological pollutants that harm marine life and human health. Plastic pollution is especially problematic, with millions of tons entering the ocean each year. Efforts to combat pollution include plastic bans, clean-up campaigns, and improved waste management. Individuals, industries, and governments all play crucial roles in reducing marine pollution. Let's work together for a healthier, cleaner ocean.
