Water is vital for survival - for that of humans, thousands of different species of non-human animals and plants, and the very Earth we all live and depend upon.
Remarkably, 95.7 per cent of the world’s water makes up the oceans - too salty for human use - with the remaining 2.5 per cent locked into the ice caps (friendsoftheearth.uk). So, we humans, along with many other creatures of Earth who can only consume fresh water, rely on such a tiny amount of this natural resource for life.
