Water is a vital, life-sustaining substance that covers over 70% of the Earth's surface. It exists in three states—liquid, solid (ice), and gas (vapor)—and is essential for all known forms of life. Water supports ecosystems, regulates climate, and is crucial for agriculture, industry, and human consumption. Its unique properties, such as high heat capacity and solvent abilities, make it indispensable for biological and chemical processes. Freshwater sources, like rivers and lakes, provide drinking water, while oceans influence global weather patterns. Despite its abundance, only a small percentage is accessible as freshwater, making conservation critical. Pollution, overuse, and climate change threaten water supplies, emphasizing the need for sustainable management to ensure future availability for all living beings.
