20 Things You Didn't Know about Water

I found all of those 20 facts about water fascinating but here are the 5 that i understood and that impressed me the most:
1. The International Space Center recycles 93% of the astronaut's perspiration and urine, changing it to potable water. This is amazing and in the future I think we could use this on Earth. Have that system in our houses or office, even schools, that would be great. It would save so much water on earth it might be one of the best inventions ever. 
2. Everybody should have hear of the myth drink 8 to 10 cups of water per day (or 2 liters) but it was never proven. It's just a simple assumption with no facts supporting it. And just imagine millions of people following it. It might be such a waste of water, and it might harm.
3. You can get intoxicated from too much water. Amateur marathon runners die because of that every year. This makes me wonder what is the exact amount we should drink. It's either to less or too much. What if 2 liters is actually too much? That can harm us? What if we are just wasting a lot of water?
4. Scientists at Oregon State University have identified vast reservoirs of water beneath the ocean floor. In fact, there may be more water under the oceans than in them. This means that if our oceans dry out (hope not)  we still have water under, even more. But if water would seem to be lacking, we could use the major amount from under. People won't or can't afford it might solve their problems. But I think we should only use this if we are in great danger or else we will take it for granted.
5. A hairy leg may get sunburned before the other because hairs, as small as they are, can carry water too. This information could prevent severe sunburns causing horrible diseases such as cancer. But I think only women could apply it. 


5 Facts:


1. Set in the desert of Dubai, the Tiger Woods Golf Course uses 4 million gallons of water every day to maintain its lush appearance.

5. Since 1950, water usage in the US has risen 127%.


By doing this we found out more about water, more facts that the movie Blue Gold told us and different connections to it. Some facts agreed other informed us better. But both showed us the same thing. We need water and we are loosing and taking it for granted. And they also agree that we MUST do something.
