Tuesday Trivia – July 31, 2018 Answer

For those who saw last week’s Tuesday Trivia post, read on for the answer you’ve been waiting for.

For those who are unfamiliar with these posts, every other Tuesday, a trivia question will get posted to allow us to test our wits and expand our horizons.

As a reminder, the question that was posed last week:

Imagine shrinking the Earth’s water supply down to 100 liters. The volume of fresh, usable water would be roughly ____(fill in the blank)____ liters.

Answer:  0.003 liters!

This may seem like a surprising answer, given that water is everywhere on the Earth – glaciers, lakes, rivers, streams, oceans and aquifers.  There’s even moisture in the atmosphere!  However, you must first take into account that most of the water on Earth (roughly 97%) is contained within our oceans which makes it salt water, not fresh water.  A significant portion of the remaining fresh water is tied up in glaciers, too polluted for safe consumption, or is buried too deep under the Earth’s crust.  Obviously, we could make attempts to clean up our polluted waters or pull fresh water out of the Earth, but those quickly become cost-prohibitive options for the planet’s growing population.

Clearly, fresh water is a precious resource for us. Click here to learn more about methods for monitoring and protecting our water sources.

Stay tuned for a new trivia question next week. In the meantime, wrack your brain for your best trivia questions and send them to me in the comments section. We’re eager to expand our horizons!
