Water & Lives

“In the world there is nothing more submissive and weak than water. Yet for attacking that which is hard and strong nothing can surpass it.”
- Laozi

  • Water is sticky. The molecules love to stick to things, especially each other. It’s what gives it such a large surface tension. It keeps you alive: it means water can pull blood up narrow vessels in the body, often against the force of gravity.
  • Water is the second most common molecule in the universe. The most common is hydrogen gas, H2.
  • There are at least 16 different kinds, or “phases”, of ice. All of them have different crystal structures.
  • Our body is between 60% and 75% water. This changes at different times of your life: a human foetus is around 95% water for the first months, getting to 77% water at birth. In a 70kg person, there are 42 litres of water.
  • Our brain contains over 80% water.
  • Each of your cell contains over 90% water. Water is crucial to cellular hydration and rejuvenation.
  • We each drink around 1 cubic metre (1000 litres) of water a year.
  • Hot water freezes faster than cold water. This is known as the Mpemba Effect, and no-one knows why it happens.
  • It takes 200 litres of water to produce the coffee beans for one cup of coffee
  • It takes 15,000 litres of water to produce 1 kg of beef.
  • It takes 100 litres to make 2 slices of bread and 65 litres to make the cheese filling in your sandwich.
  • It takes 150 litres of water to make a pint (568ml) of beer.
  • A kg of cotton – enough for a shirt and a pair of jeans – needs 10,000 litres of water to produce.
  • If we are using hands to wash dishes, we will be using up 7 times more water that what a modern dishwasher machine uses!
  • We spend more water on our recreation than for our survival needs. In America, an average golf course, in a single day, uses 1,180,000 litres of water for maintenance!
  • To grow enough oranges that can be used for making a glass of orange juice, it takes 50 glasses of water.

Do you know how much much new water will be created on earth in next million or zillion years? Well, NONE! The amount of water that is present on earth was already there and it will be there. No new water will be formed. Please consume wisely!
