All the water in the world

globe with all surface water collected into a small dropletThis stunning image brought home for me the preciousness of water.

We believe we are the blue planet, seven-tenths covered in water; and yet all the water collected together from the air, rivers and oceans – the water we depend on – forms this tiny droplet.

You can see the full image here.

For some this image may simply be a representation of known information in a new and surprising way; for others it might be a ‘wake up’ moment’ – in the same way that the Earthrise photograph (taken by the Apollo 11 space crew) has been dubbed the most influential environmental photograph ever taken.

Or do you remember your first reaction to this statistic: if every human being wants to live like western Europeans, we’ll need three planets to provide all the necessary resources and to cope with the waste. And make that five planets if we all want the lifestyle of North Americans.

It is known that information, on its own, is rarely enough to change behaviour. Images and statistics can sometimes help, though, in bringing a message home.

Drink of water, anyone?
