Two thirds is stored in ice caps and glaciers. The remaining portions are found as deep ground water (30%) or in surface waters (rivers, lakes, and shallow ground water) (. 389%).

Fresh water used increasingly for agriculture (70% of water use with 40% efficiency) and industry. Population pressures in many developing countries, with insufficient water for drinking, washing, sanitation, and agriculture, leads ot mass migrations and hardship. More efficient use of fresh water would increase agricultural production, especially in developing countries o. Approximately 70% of human body is comprised of water.
