Water is a vital resource that covers about 71% of the Earth's surface. It exists in various forms, including rivers, lakes, and oceans, and is essential for all known forms of life. Without water, ecosystems would collapse, and human survival would be impossible. In addition to its biological importance, water plays a crucial role in agriculture, industry, and energy production. It is used for drinking, irrigation, and generating electricity through hydroelectric power. The management and conservation of water resources are critical to ensuring a sustainable future for our planet.
