All the water and all the air

Left: All the water in the world (1.4087 billion cubic kilometres of it) including sea water, ice, lakes, rivers, ground water, clouds, etc.
Right: All the air in the atmosphere (5140 trillion tonnes of it) gathered into a ball at sea-level density. Shown on the same scale as the Earth.

This reveals how very fragile our world is. Imagine trying to keep this balanced. I can imagine both (and therefore mankind), hopelessly disrupted with one wrong move.
