I went to a  to have a physcal check today,

and I waited for my turn while reading a medical magazine .

There was a topic about global warming in the magazine.

Global warming is one of the current biggest problem, isn't it?

 

Weeeeeell!!!

There are about  billion people in this world, right?

A human being does normally fart of cups of glasses a day.

This means about  billion liters fart are exhausted on the Earth by 6 billion people< what a stinky Earth!!!

 

Fart is kind of methane, of course.

and methane is one of the causes of global warming

 

Ummmmm

We should stop farting any more!!!!!!!!!!

SAVE OUR EARTH!     <hehehe
