An amazing comparison: all the water and all the air in the world
Comparisons are the 'soul' of infographics. A good visual comparison can say more than thousands of features. This is one of the good ones. If I say there are 1.4087 billion cubic kilometres of water and 5140 trillion tons of air on Earth, I think not many pople can have an idea about how much is that. The two balls in the maps represent all the water (left) and all the air (right) at the same scale as Earth. Amazing!
