Water of Life
Why are scientists always looking for water on other planets? Because life can’t exist without water! NASA's Jet Propulsion Laboratory writes, "Liquid water is a necessity for every form of life known. With this in mind, scientists are eagerly searching for liquid water in places other than Earth."
Each creature on this planet requires different amounts of water for survival. We humans require about 2.5 quarts of water per day. Without it, our blood thickens, we become dehydrated and quickly die. You could probably last over a month without food, but won’t make it a week without water!
Some animals are much tougher than us when it comes to survival in dry climes. The Kangaroo Rat never drinks, but gets all the water it needs from eating seeds. And we all know about the famous camel that can trek across the hot deserts for months without taking a drink.
On the opposite end of the spectrum, the jellyfish not only lives in water, but is nearly entirely composed of water. This squishy ocean creature is about 95% water and 5% organic material. When you see a jellyfish stranded on the beach, he will soon disappear under the hot sun, evaporating into the sky. Water is certainly most essential to his life!
