These remarkable images by Adam Nieman give us some impression of the true scarcity of the vital natural resources available to us on this planet.

Viewed like this you can see that the vast oceans and endless sky are merely the thinnest of skins adorning the Earth.

These are the resources that we have to live within and share with every other living organism on Earth This is also where a lot of our waste goes, in these very finite environs.

Great clip, Lembit, thanks!

Has this taken into account the vast volumes of underground water?

Answering my own question, the source does say 'ground water' so will assume they are taking into account underground water as 'ground water'
