I'm curious how a similar ball would compare containing all the biomass on 
planet earth (humus, et. al.).

...yet a lot of people piss in several gallons of potable water and flush 
it?! how irrational.  water is so precious.

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.
