Water pollution occurs when harmful substances, such as chemicals, pathogens, or waste, contaminate freshwater sources, adversely affecting ecosystems and human health. It results from various activities, including industrial discharge, agricultural runoff, and improper waste disposal. Consequences of water pollution include reduced access to clean drinking water, harm to aquatic life, and ecosystem disruption. Mitigation efforts involve stricter regulations, sustainable practices, and public awareness campaigns to safeguard our vital water resources.
