"Sweet Water" refers to water that is low in salt content, making it suitable for drinking and irrigation. It is found in rivers, lakes, and underground aquifers. This type of water is essential for human survival, agriculture, and maintaining ecosystems. In contrast to saltwater, which is found in oceans and seas, sweet water is vital for freshwater habitats. It supports various life forms, including plants, fish, and wildlife. The availability of sweet water is crucial for communities, as it directly impacts health, food production, and overall quality of life.
