Water might seem like an abundantly available resource, but in actuality only one percent of the world's water supply is fit for human consumption. Furthermore, 90 percent of the world's fresh water is trapped in glaciers found in Antarctica, and is therefore considered unusable.
In developing nations, the task of collecting water is given to the women and children who spend an estimated total of 140 million hours a day--while walking an average of 3.7 miles--collecting water. People living in poorer countries regularly drink contaminated water due to unavailable sanitation facility services. The consumption of improperly sanitized water poses serious health risks that result in more than 840,000 people dying from water related diseases each year.
Humans are able to survive for a month without food but only a week without water. However, consuming as much water as possible is not advisable. Although approximately 70 percent of the human body is made of water, and the daily recommended intake of water is eight cups, water intoxication can occur if a large volume of water is consumed too quickly.
Water conservation efforts take precedence among global environmentalist organizations, as it is predicted that half the world's population will live in countries with high water stress by the year 2025.
