World Water Day is observed on March 22 every year to raise awareness of the water crisis facing much of the world's population. The U.N. estimates that more than 2 billion people live without safe drinking water at home; affecting their health, education and livelihoods. Instead of turning on a tap, they must spend countless hours queueing or trekking to sources of water. This water is often contaminated, putting people at risk of infectious diseases and premature death.

People who have plentiful access to water are encouraged to try not turning on their taps all day. Water is a finite resource that is fundamental to human well-being. Don't waste it.
