Drinking Water...Interesting!

Water, we can like or not to drink it. Personally me that is the only thing I drink mostly, other than juice and milk (on occassion). Heres what wikipedia-say about water (i put the interesting stuff below on what I thought)

Excluding fat, water composes approximately 70% of the human body by mass.

Throughout most of the world, the most common contamination of raw water sources is from human sewage and in particular human faecal pathogens and parasites. In 2006, waterborne diseases were estimated to cause 1.8 million deaths each year while about 1.1 billion people lacked proper drinking water.

70% of the Earth's surface is covered by water.
Sources where water may be obtained include:
-ground sources such as groundwater, hyporheic zones and aquifers.
-precipitation which includes rain, hail, snow, fog, etc.
-surface water such as rivers, streams, glaciers
-biological sources such as plants.
-the sea through desalination

Humans can survive for several weeks without food, but for only a few days without water.

Only forty-six percent of people in Africa have safe drinking water.

Drinking water vending machines in Thailand. One litre of purified water is sold (into the customer's own bottle) for 1 baht.
