Survival skills
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise.
Space Saves Society
Water covers the largest percentage of our planet’s surface and it is vital for our survival. However, many areas still suffer from absence of drinking water. The Water Supply and Sanitation Collaborative Council (WSSCC) refers that “Today 2.5 billion people, including almost one billion children, live without even basic sanitation. Every 20 seconds, a child dies as a result of poor sanitation. That's 1.5 million preventable deaths each year.”
