I think it’s safe to say that pretty much everyone knows by now that wasting water is a bad thing. In general, we know we should turn off the tap whilst brushing our teeth, only boil as much water as we need for a cup of tea, and take shorter showers in place of deep baths.
And whilst all of these things are important, they really are (steady yourselves for the upcoming predictable pun) just a drop in the ocean. Evidence suggests that we are approaching a global water crisis:
- Only 3% of the world’s water is fresh water, and two thirds of that is locked away in glaciers and other inaccessible places.
- At the current rate of consumption, two thirds of the world’s population may face water shortages by 2025.
