Here is a picture that made me think... I found it on the blog of Dan Phiffer.

On the left Earth, the volume of the ball sitting on Europe represents the total volume of water existing on our planet (sea water, ice, lakes, rivers, ground water, clouds).

On the right one, the volume of the ball represents all the air of our atmosphere (at sea level density).

I was a bit surprised regarding the volume of water, so I did the calculus myself : 1.4 billion cubic kilometers of water, that's a 1387 kilometers diameter sphere... From which only 1% of liquid fresh water.

So, and of my ecologist story... Back to the usual concerns of ShamWerks...

*Be sure that if I see anyone of you guys, dumping his wasted oil down in the nature, he'll get my fist in his face...*
