While fighting dehydration by guzzling water, I came upon some interesting facts about water.
- Although water covers about 71% of the earth’s surface, only 3% is fresh water. For a perspective, if all the earth’s water fit in a gallon jug, the drinkable fresh water would be about 1 tablespoon.
- Frozen water (ice) is about 9% lighter than water. That’s why ice floats.
- The human body is about 66% water. Human blood is about 83% water. The brain is about 75% water. Bones are about 25%.
- An elephant is about 70% water.
- On average, a single tree provides about 75 gallons of water per day in evaporation.
- Humans use about 50 gallons of water per day. Americans use more water per day than Europeans.
- In America, water used around the house (cooking, cleaning, laundry, drinking, toilets, yard watering) makes up only 1% of total water usage.
- It takes about 49 gallons of water to produce 1 glass of milk.
- A bit over 39,000 gallons of water are needed to manufacture a car, including its tires.
- Pollution of fresh drinking water is a problem for half of the earth’s population.
Now I am quite parched; gotta get a drink of H2O.
