The availability of water on the Earth is said to be the reason the planet is able to sustain life. This simple substance is the combined need of all living things and it covers the major portion of the planet as well. Its uses include drinking to quench thirst, irrigation to support food production, as an agent to put out fire, sewage disposal and uses of a more modern nature such as for rotating thermal turbines for power generation and recreational purposes. It was aptly termed by some Greek philosophers to be the source of all existence. Thus in the modern world as it was in the ancient, water remains an important natural resource without which humans cannot survive.
The world is already seeing wars being waged for a crucial resource such as oil which is not even necessary for sustaining life. If water becomes the object of a similar conflict, it could prove to be much more disastrous considering its importance for humans.
