WATER and STATES OF MATTER



Water is life itself, but we are using too much of it. We use it for drinking, washing, transport, electricity, farming and recreation. Only 3% of water on the planet is fresh and just a third of that is accessible to humans. There's been a 35% decline in freshwater species since 1970. we need to harness rivers, lakes and aquifers in ways that won't cause long-term harm. Freshwater ecosystems are worth trillions of dollars each year. They provide food and livehoods for millions. So we should make choices that ensure people and nature have enough water.
