The document discusses water resources around the world. 97% of water is salt water found in oceans, while 3% is fresh water that humans rely on. Water moves through a natural cycle of evaporation, transpiration by plants, condensation into clouds, precipitation as rain or snow, and groundwater. India faces challenges of increasing water demand, droughts, floods and declining groundwater levels. The National Water Mission aims to conserve water, minimize waste, and ensure more equitable distribution of water resources across and within states.
