Water is a tasteless and colourless substance essential for all forms of life that live in planet earth.
Our planet is covered in water, it exists in many places and forms, such ass in oceans, polar ice caps, clouds, rain water, rivers and freshwaters.
Humans consume drinking water, which is water that has qualities that are essential for the human body. Rain water in many countries is polluted and therefore not safe to drink. This natural resource has become scarce with the growing world population, and its availability is a major social and economic concern.
