Saving Water is a Cinch!

Water is the single most important natural resource on Earth. And though 72% of our planet is covered in water, we cannot take it for granted. Instead, we must be careful to use water only when necessary. The less water that we waste, the more clean water we will have in the future.
There are a number of ways to save water. The best place to start is in the bathroom. Why? Because studies show that three-fourths of the water we use indoors is used in the bathroom. Therefore, it is in the bathroom where we should pay close attention to our habits.
For example, what do you do when washing your hands? Many people turn the water on and then lather up with soap while the faucet is running. No big deal, right? After all, washing your hands takes only ten seconds or so.
But then, imagine how many times in your life you will wash your hands. Now imagine how much water you will save by turning off the faucet while you lather up with soap. Talk about an easy way to save a huge quantity of water!
In general, saving water involves changing only a few wasteful habits. Most people find that these habits are actually pretty easy to change. Give it a try yourself and you’ll agree: saving our most important natural resource is easy!
