Groundwater is mostly non-renewable, study finds

[SlyPokerDog]

Less than 6% of groundwater is replenished within 50 years

The water that supplies aquifers and wells that billions of people rely on around the world is mostly a non-renewable resource that could run out, a new Canadian-led study has found.

While many people may think groundwater is replenished by rain and melting snow the way lakes and rivers are, underground water is actually renewed much more slowly.

In fact, just six per cent of the groundwater around the world is replenished within a "human lifetime" of 50 years, reports University of Victoria hydrogeologist Tom Gleeson and his collaborators in a new study published in the journal Nature Geoscience today.

That water tends to be mainly found within a few hundred metres of the surface, where it is most vulnerable to being contaminated by pollution or depleted by higher temperatures and reduced rainfall as a result of climate change, the researchers found.

"Groundwater is a super-important resource," Gleeson said in an interview with CBC News. "It's used by more than a third of the world's population every day for their drinking water and it's used by agriculture and industry."

Chicken Little likes to walk in the woods. She likes to look at the trees. She likes to smell the flowers. She likes to listen to the birds singing.

One day while she is walking an acorn falls from a tree, and hits the top of her little head.

- My, oh, my, the sky is falling. I must run and tell the lion about it, - says Chicken Little and begins to run.

She runs and runs. By and by she meets the hen.

- Where are you going? - asks the hen.

- Oh, Henny Penny, the sky is falling and I am going to the lion to tell him about it.

- How do you know it? - asks Henny Penny.

- It hit me on the head, so I know it must be so, - says Chicken Little.

- Let me go with you! - says Henny Penny. - Run, run.

So the two run and run until they meet Ducky Lucky.

- The sky is falling, - says Henny Penny. - We are going to the lion to tell him about it.

- How do you know that? - asks Ducky Lucky.

- It hit Chicken Little on the head, - says Henny Penny.

- May I come with you? - asks Ducky Lucky.

- Come, - says Henny Penny.

So all three of them run on and on until they meet Foxey Loxey.

- Where are you going? - asks Foxey Loxey.

- The sky is falling and we are going to the lion to tell him about it, - says Ducky Lucky.

- Do you know where he lives? - asks the fox.

- I don't, - says Chicken Little.

- I don't, - says Henny Penny.

- I don't, - says Ducky Lucky.

- I do, - says Foxey Loxey. - Come with me and I can show you the way.

He walks on and on until he comes to his den.

- Come right in, - says Foxey Loxey.

They all go in, but they never, never come out again.

That is because it is all in big plastic jugs at Sams Club. How many billions of gallons do we keep captive every day?

You should've said "water lives matter"
