Water Pollution

Water pollution is caused when untreated sewage, industrial waste, chemicals, and plastic are dumped into rivers, lakes, and oceans. Polluted water becomes unsafe for drinking and spreads diseases like cholera and typhoid. Aquatic life suffers as fish and other organisms die due to lack of oxygen and toxic substances. Water pollution also affects agriculture and food supply. Preventing water pollution requires proper waste treatment, reduced use of chemicals, and public awareness about keeping water bodies clean.
