Facts about water
Interesting facts about water
We can’t imagine life without water (before you disagree, please don’t forget beer is also for the most part made of water) and I decided to put together a post about water facts, accompanied with some of the best photos available on-line.
All photos are of course public domain and royalty free, but I wouldn’t mind if you give me a nice credit for anything interesting you might find on this page.
Here we go with some fascinating numbers:
– more than 70 percent of Earth’s surface is covered with water,
– there is more water under the surface than on the surface,
– human body is 70 percent made of water (newborns even more),
– only 3 percent of water on our planet is drinkable (most of it we use it for washing, watering and other non-drinking related goals),
– quality standards of drinking water are falling rapidly.
Water and health:
– we can live without food for months, but without water for only about a week,
– if we drink too much water, we can destroy the balance of electrolytes in organism and die,
– every fourth person on Earth doesn’t have daily access to clean, drinkable water,
– more than four millions of people die every year because of water related diseases,
– four out of five diseases in developing world are directly related with water,
– regular hands washing is single and most effective prevention for most of diseases.
And now for the statistics…
