There is one substance in this world that is the essence of life – Water. We all depend on water, says Green Water Technologies, and water is everywhere. In fact, 70 percent of our planet is covered in water and nearly 70 percent of the human body is comprised of water. Humans typically need to drink at least 2 liters of water a day to enjoy maximum health.
Earth is the only planet, as far as we know, covered in liquid water. Green Water Technologies notes that water’s life-giving chemistry has nurtured life on Earth for billions of years. It’s possible that life first developed in its warm waters. From space, the beauty of our water world is beyond words. This unique water chemistry is truly special to our world.
Water exists as a gas, a liquid and a solid. Unlike other substances, which expand on heating, water expands on freezing.
