The volume of fartgass discharged into the athmosphere is far more disturbing than CO2. 140 billion farts are squezed out everyday, making it 51 trillion farts a year. What are we gonna do with this vast volume of stinky? Breath it? Feed it to the plants? Store it underground as atomic fart?
How much fart gass can our biosphere take? Well, nobody knows. Untill then Global Watch suggests we all squeeze it, install our own butt plugg or take it out as a burp before we fart ourselves into destruction.
