People who publish numbers should try to be a bit  more numerate:

Each human emits on the order of 1 kg of CO2 per day due to normal  
breathing, or about a third of a ton per year.  So if we are to  
believe this rather extreme and supposedly alarming analysis, total  
worldwide spam at 17m tons is eclipsed by human breathing in a  
relatively small country of about 50m people.

Some have estimated that 1,000m people use the Internet today,  
worldwide. (their breathing alone accounting for >300m tons). So the  
spam problem is roughly equivalent to having those people who actually  
use the Internet do a little more exercise than they normally do.

Let's focus on some *real* problems.  Symantec's desire to scam  
stimulus money should be treated with the huge lack of respect it  
deserves. Flush it in the crapper.
