In past years -- generally on Earth Day -- the American Mustache Institute has demonstrated its interest in environmental stewardship.

Indeed, our annual greening tips  are the thing of lore.

Now, as part of our award winning series of Monthly Mustache Interviews -- we interview one of the few clean-shaven slobs we've allowed to access our reach: Forbes magazine writer Chris Steiner, who has a new book out called "$20 Per Gallon" about the impact of rising fuel prices on American culture.

Despite his seeming hatred of the Mustached American lifestyle, it's an interesting read, even for those of us who do not read.

Check out our interview with Steiner here. 

Carry on.
