It’s that time of year again. Everyone’s favorite holiday - World Water Day! What? Never heard of the holiday that celebrates the one substance that is the basis for all life? Think about it, when scientists are looking for proof of life on other planets, what is the one clue they hope to find? Water. The simple presence of water. They know that if there is water, there may be a possibility for life. No water, no life.
Here on Earth, almost three quarters of our planet’s surface is covered with water. The volume of water in your own body is made up of almost that exact same percentage. We all need water to survive. And by “we all,” I mean microbes, insects, kittens, people, polar bears, trees, frogs, flowers, birds, turtles, forests, ecosystems, etc. We are all intricately linked through water. As much as we try to separate these groups in our minds, as much as we disassociate ourselves with parts of the rest of the world, it would do us good to remember that we all have one common need.
What do sharks and humans have in common? Their need for water. Clean water.
There is some great information now available that helps us visualize how truly dependent we are on water. We can see how much water it takes to make a one pound of beef, one pint of greek yogurt, one cup of coffee. It’s all very fascinating – mostly because it forces us to look at water in new ways. We live in a world where “conserve water” or “save water” used to mean - stop letting the faucet run while you are brushing your teeth, or don’t water your lawn in the middle of the hot summer day.
This new view of water, puts a truer value on the resources required to produce the food we eat and makes us think about our daily choices in different ways. For example, it takes three eggs to equal the amount of protein in one serving of beef, but the beef requires nine times the amount of water to produce.
If we are committed to being good stewards of this amazing water planet, we need to start with our own daily choices. Figure out what is most important to you and then look for ways to make less of an impact!
