1. As oceans are very wide and there are multiple to be found on earth, oceans store most of the earth's water. This is apparently 97% of the total amount of water on earth, 2% of which is frozen.
2. 80% of the earth's water is surface water. The other 20% is either ground water or atmospheric water vapour.
3. Of all the water on earth, only 2,5% is fresh water. Fresh water is either groundwater (0,5%), or readily accessible water in lakes, streams, rivers, etc. (0,01%).
4. If all the world's water were fit into a gallon jug, the fresh water available for us to use would equal only about one tablespoon.
5. Over 90% of the world's supply of fresh water is located in Antarctica.
6. Less than 1% of the water supply on earth can be used as drinking water.
7. The earth's total amount of water has a volume of about 344 million cubic miles.
· 315 million cubic miles is seawater.
· 9 million cubic miles is groundwater in aquifers.
· 7 million cubic miles is frozen in polar ice caps.
· 53,000 cubic miles of water pass through the planet's lakes and streams.
· 4,000 cubic miles of water is atmospheric moisture.
· 3,400 cubic miles of water are locked within the bodies of living things.
8. Approximately 66% of the human body consists of water. Water exists within all our organs and it is transported throughout our body to assist physical functions.
9. The total amount of water in the body of an average adult is 37 litres.
10. Human brains are 75% water.
11. Human bones are 25% water.
12. Human blood is 83% water.
13. 75% of a chicken is water.
14. 80% of a pineapple is water.
15. 95% of a tomato is water.
16. 70% of an elephant is water.
17. Each day the sun evaporates a trillion tons of water.
18. A single tree will give off 265 liters (70 gallons) of water per day in evaporation.
19. An acre of corn will give off 15,000 litres (4,000 gallons) of water per day in evaporation.
20. A small drip from a faucet can waste as much as 75 litres of water a day.
21. The amount of water we deliver on a hot summer day, 308 million litres (80 million gallons), could fill 1.28 billion cups of coffee.
2. A person must consume 2 litres of water daily to live healthily. Humans drink an average of 75.000 litres of water throughout their life.
3. Humans cannot drink salt water.
4. More than 2 billion people on earth do not have a safe supply of water.
5. Water regulates the temperature of the human body. If you have caught a fever you should drink lots of water.
6. Water removes waste from the human body.
7. You should never drink water straight from a lake or river, as it can be damaging to your health.
8. If you live in an old house with lead pipelines you could get health problems. Due to weathering of the pipelines lead can end up in your tap water.
9. Your drinking water may be fluoridated to help prevent dental cavities.
10. Water leaves the stomach five minutes after consumption.
11. Centres for Disease Control receive notification of more than 4,000 cases per year of illness due to drinking water contamination.
12. A quarter of the world's population is without safe drinking water.
13. Water can cause serious health damage when it is contaminated by bacteria and other microrganisms.
14. In most cities and towns, drinking water from the tap is treated so that people don't get sick with diseases such as cholera and typhoid, which are caused by bacteria, viruses or parasites found naturally in the water.
