Water is consumed by billions of people each day but that doesn't mean that it isn't scarce. Water can be destructive but beneficial, it is both positive and negative in numerous ways around the world.
Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commonly obtained include springs, hyporheic zones and aquifers (groundwater), from rainwater harvesting, surface water (from rivers, streams, glaciers), or desalinated seawater.
