How does population growth negatively impact water quality?

Population growth often leads to increased urbanization and industrial activities, which can result in higher levels of pollutants entering water sources. As more people require water for consumption, agriculture, and sanitation, the demand on existing water supplies escalates, leading to over-extraction and potential contamination. Additionally, increased waste generation from larger populations can overwhelm sewage systems, causing untreated wastewater to contaminate rivers and lakes. This deterioration in water quality can harm ecosystems and pose health risks to communities.
