How much do you know about our planet’s water supply? It might be a lot or very little, but how much you know is not as important as how much you care. Our water supply is a precious resource because it is what sustains life for all the living beings, human or otherwise, here on Earth.
So let’s start with the easy stuff. How much of the earth’s surface is covered by water? About 80%. You knew that one, right? See how many of the next group you can guess correctly. The answers are at the bottom of the post.
- What is the most common substance found on earth?
- How much of the earth’s water supply is drinking water?
- How many gallons of water are dropped by an inch of rain?
- How much water does a dairy cow drink to be able to produce a gallon of milk?
- Which uses more water, the average dishwasher or an average person washing dishes by hand?
- How long can a person live without drinking water?
- How many gallons of water does the average person use in one day?
- What is the annual cost to supply water to all U.S. citizens?
- How much does a gallon of water weight at room temperature?
- What percentage of the human body is made up of water?
So how did you do? I must confess I did not know a lot of these fun little bits of trivia either. Our most important natural resource often gets forgotten about or left out of the discussion entirely. So next time you turn on the tap stop and think about the importance of our water supply and how we all have to work together to keep it clean.
