This document discusses water pollution. It defines water pollution as any changes in water's physical or chemical properties that negatively impact living things. Common causes of water pollution include chemical waste, sewage, and plastic. With billions of people, disposing of sewage waste properly is challenging, and according to the WHO, 11% of the world's population lacks access to clean drinking water. Industries also pollute water by discharging untreated effluents containing harmful chemicals. While education and laws can help address pollution, cross-border pollution shows international cooperation is also needed to fully solve the water crisis.
