Scientists, known as astronomers, have found evidence of water in many places in the universe, including the moon, Mars, Jupiter’s moons, comets and interstellar clouds. The earth is blue when seen from space. That’s because of all the water that’s on our planet.
Water on Earth
Ninety-seven percent of the water on Earth is salt water, like you find in the ocean. Only 3 percent of the earth’s water is fresh or drinkable, and two-thirds of that is in the form of ice, like the polar ice caps, or deep underground.
The human body
Did you know that about 75 percent of the human body is water? Your body temperature is controlled by water. When your body loses water, it becomes dehydrated and your body temperature rises, and drinking water isn’t the only way for you to get fluids into your body. Eating fruits and vegetables also helps. Two-thirds of the human brain is made up of water. Drinking plenty of liquids keeps your brain working.
Vegetables that are boiled actually lose some of their water content, weighing less after boiling in water than they did before. Steaming vegetables instead of boiling helps retain the vegetables’ water content and its vitamins.
When water is boiled, it vaporizes into steam. The boiling point for water is 212 degrees Fahrenheit or 100 degrees Celsius.
Use a broom
Using a water hose to clean your sidewalk or driveway is a waste of water. Use a broom instead.
Color of water
Water is colorless in small amounts, but can have a bluish color in larger quantities, like in a pool. Water is essential for all living things to survive.
The water we drink is constantly being recycled, or reused. In fact, the water that was on the earth during the prehistoric times is the very same water we still use today. Think about that.
Freshwater doesn’t come easy to everyone. About 2 billion people in the world spend an average of three hours a day just getting their water.
A dishwasher uses an average of 11 gallons of water when it runs. That’s a lot of water. To save water, always make sure that the dishwasher is fully loaded before you run it.
Never waste water
Never put water down the drain when there may be a use for it, such as watering plants or cleaning.
The best time to water plants outside of the house is during the cooler hours of the day, early in the morning or late in the afternoon. Avoiding the heat can prevent the water from evaporating too soon.
Installing low-flow faucets in your kitchen and bathroom can help save a lot of water.
A steady drip of water from your faucet can waste as much as 20 gallons of water a day.
Americans drink more than 1 billion glasses of tap water a day. Always keep a pitcher of water in the refrigerator. That way, you don’t have to let the faucet run while you wait for your water to get cool.
Scraping dishes into the trash rather than rinsing them before loading the dishwasher is another smart way to conserve water.
