Clean water is water that is free from harmful contaminants and pollutants. It is essential for human health, as it prevents diseases and supports bodily functions. Clean water is necessary for drinking, cooking, and sanitation, making it a vital resource for communities around the world. Access to clean water is a significant global issue. Many regions, especially in developing countries, struggle with water scarcity and contamination. Organizations like the World Health Organization and UNICEF work to improve water quality and promote safe drinking practices to ensure that everyone has access to this essential resource.
