D o you like water? No, you prefer soda? Well, would you shower in Coke? Wash your dishes in Sprite? Didn’t think so. Of course you like water! It’s the world’s most precious resource. Without it, we wouldn’t survive very long. So it’s a good thing that water makes up more than 70% of the planet because that means there’s plenty of water to go round, right?

Well, actually, most of that water (96% to be precise) is in the oceans, where it’s not really useable. Freshwater, which is drinkable water, makes up only 2.5% of the world’s water. So you can see why a lot of governments and environmentalists around the world are getting worried about the water situation.

The good news is that there are lots of ways to make the most of the water we use so that it doesn’t go to waste.
