National Geographic won a journalism graphics award for an amazing interactive map showing where fresh water comes from on Earth. This is just a taste of what you can find if you visit the map, which shows locations of glaciers, rivers, aquifers, and more. In this part of the map, you can see where groundwater is - and find out that it's not being recharged fast enough to meet local demands.
Too bad we didn't have this graphic on World Water Day.
On a semi-related note, I was talking to my Grade 1 class about World Water Day. Nothing too much, we just talked about where the water in the tap comes from, how sadly not everyone in Canada can drink the water from their tap without boiling it, and that in other countries, some people don't have plumbing at all.
Then I sat there stunned, while one of my Grade 1's launched into a description of a machine he said he wanted to build. He said it would have three buttons, one for sucking up water, one for blowing the water back out, and the third one for melting ice so you could suck up any water that was ice. He described how he would use his machine to suck up all the Earth's water. (He was a little vague on where was going to put all the water, but give him time, he's 7.)
I never expected I would be teaching a future James Bond villain. :D
