Freshwater is water that has low concentrations of salts, making it essential for drinking, agriculture, and many ecosystems. It is found in rivers, lakes, and underground aquifers. Unlike saltwater, which makes up about 97% of the Earth's water, freshwater is crucial for sustaining life on land and supporting various habitats, such as wetlands and forests. The availability of freshwater is vital for human activities, including farming and industry. However, many regions face challenges like pollution and overuse, threatening this precious resource. Protecting freshwater sources is important for ensuring a healthy environment and a sustainable future for all living beings.
