A Thread Full of Fun and Interesting Facts (well, one fact at least)

In about 3.2 years, the total methane from the combined fart of all human kind equals the weight of the empire state building.

Each person farts .5 liters a day.

There are about 7 billion people on the planet = 3,500,000,000 liters of farts a year.

7% of a fart is methane = a total of 245,000,000 liters of methane a year.

Converted to pounds = 227,850,000 pounds of methane a year

The empire state building - 730,000,000 pounds.

730,000,000 divided by 227,850,000 pounds of fart methane a year = 3.2 years
