"Water is the basis of life and the blue arteries of the earth! Everything in the non-marine environment depends on freshwater to survive."
Do you know that about 70 percent of an adult's body is made of water? Do you know that without water we can only last for 2 to 10 days? (Depending on the max daily temperature)
Do you also know that 2/3 of our mother Earth is also made of water?
However of all the water on the earth, human can only use about three-tenths of a percent of this water.

Now for a little science:
It has been shown that if you lose just 2.5% of your body weight from water loss, you will lose 25% of your efficiency. For a 175 pound man that is only about two quarts of water. As the survivor dehydrates, his blood becomes thicker and loses volume. This causes the heart to work harder and circulation of blood to be less efficient. In a survival situation, losing a full one quarter of your physical and mental abilities due to dehydration could mean the end of your life
| Max Daily Temperature | Number of Days in the Shade | |||||
|---|---|---|---|---|---|---|
| No Water | 1 Quart 0.95 Litre | 2 Quarts 1.90 Litres | 4 Quarts 3.79 Litres | 10 Quarts 9.46 Litres | 20 Quarts 18.93 Litres | |
| 120 F / 48.9 C | 2 days | 2 | 2 | 2.5 | 3 | 4.5 |
| 110 F / 43.3 C | 3 | 3 | 3.5 | 4 | 5 | 7 |
| 100 F / 37.8 C | 5 | 5.5 | 6 | 7 | 9.5 | 13.5 |
| 90 F / 32.2 C | 7 | 8 | 9 | 10.5 | 15 | 23 |
| 80 F / 26.7 C | 9 | 10 | 11 | 13 | 19 | 29 |
| 70 F / 21.1 C | 10 | 11 | 12 | 14 | 20.5 | 32 |
| 60 F / 15.6 C | 10 | 11 | 12 | 14 | 21 | 32 |
| 50 F / 10.0 C | 10 | 11 | 12 | 14.5 | 21 | 32 |
Therefore, the daily recommended of water needed by us every day in this equatorial country is eight cups per day. Not all of this water must be consumed in liquid form since every food or drink item we consumed provides some water to the body.
