Healthy, clean drinking water is something that most people take for granted. But the fact is that drinking water and healthy drinking water can mean different things to different people depending on where they are in the world.

As some of the below data reveals, some people have little to no access to clean water and it affects every aspect of their lives. Next time you leave the sink on while brushing your teeth or take an extra two minutes in the shower, just remember that there is a finite amount of fresh water in the world and the stresses of an increasing human population will only make access to clean water that much harder in the future.
