Water is a vital element of our planet and all that inhabit it. However, this essential resource has been poorly-managed, wasted and polluted for centuries by all mankind. We use it in the far corners of the world to supply our factories, take away our waste, wash ourselves, travel, or even simply for enjoyment. We are becoming increasingly aware that any water unfit for consumption that returns to the environment is inextricably linked to the water we consume. Even if we in the developed world are managing to clean our used water, in poor countries water which is fit for consumption is all too often an inaccessible resource, even a privilege.
