I found these water conservation posters online a few years ago and have been holding onto them. Many cities and other organizations create marketing materials to educate people about water conservation. In this day and time, it is strange to think about getting people to conserve water for the good of their nation, particularly for a war effort.

Drinking water with meals can impair digestion
Most of us have heard it a hundred times: drink eight glasses of water a day to stay healthy and hydrated. And while hydration is genuinely important for our health, if you’re guzzling all that water with your meals it can actually have a negative impact on your digestion.
Eight reasons why water fluoridation has failed modern civilization
If you went up to the average person on the street today and tried to explain that most Americans drink, bathe in, and wash their dishes and clothes in an industrial waste product that is linked to causing endocrine disruption and cancer, you might be labeled a loon.
Bats use water ripples to hunt frogs
As the male túngara frog serenades female frogs from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats, according to researchers from The University of Texas at Austin, the Smithsonian Tropical Research Institute (STRI), Leiden University and Salisbury University.
A túngara frog will stop calling if it sees a bat overhead, but ripples continue moving for several seconds after the call ceases. In the study, published this week in the journal Science, researchers found evidence that bats use echolocation — a natural form of sonar — to detect these ripples and home in on a frog. The discovery sheds light on an ongoing evolutionary arms race between frogs and bats. Read more
Idea inspired by breath-freshening strips leads to water test for the world
Inspiration can come in many forms, but this one truly was a breath of fresh air. A group of McMaster researchers has solved the problem of cumbersome, expensive and painfully slow water-testing by turning the process upside-down.
