Since the very birth of human civilisation, people have moved to settle close to water. People move when there is too little of it. People move when there is too much of it. People journey down it. People write and sing and dance and dream about it.
People fight over it.
And all people, everywhere and every day, need it. We need it for drinking, for cooking, for washing, for food, for industry, for energy, for transport, for rituals, for fun, for life. But we stand today on the brink of a global water crisis. More people lack drinking water today than they did two decades ago. More and more freshwater sources are being used-up and contaminated.
