"We breathe it out"

In reply to Al Gore's new film, some oil-funded outfit calling itself the Competitive Enterprise Institute has produced two of the stupidest commercials ever made.
Just go take a look -- you'll think they are SNL parody ads, but they're not. Their message is that carbon dioxide just can't be bad for us because "we breathe it out."
Oh, yes..."out" is, of course, the operative word here.
They just don't get it, do they?
Media Matters writes :

It’s comforting to know that this is the best global warming rejectionists can come up with. There are plenty of things that are healthy and essential in reasonable quantities but harmful in extremely large quantities. (For example, drinking a few glasses of water is beneficial. Drinking 10 gallons of water can kill you.)

Media Matters also points out that the p. r. flacks who wrote the second commercial don't even understand the meaning of the glacier research they are quoting.
