Water pollution occurs when harmful substances such as chemicals, plastic waste, sewage, and industrial waste enter rivers, lakes, and oceans. This pollution makes water unsafe for drinking and damages aquatic ecosystems.

Polluted water affects all living beings on Earth. Humans can suffer from diseases like cholera and typhoid by drinking contaminated water. Fish, birds, and other aquatic animals may die due to toxic substances and lack of oxygen in water. Plants and crops can also be harmed when polluted water is used for irrigation.

To minimize water pollution, we should avoid throwing waste into water bodies, reduce plastic use, treat sewage and industrial waste before discharge, and conserve water. Planting trees and spreading awareness about clean water practices can also help protect our water resources for future generations.
