how poetry could save the planet

According to an online article from Scientific American, simply posting "toilet poems" at eye level in stalls helps cut down on the use of toilet paper, thus fighting global warming -- or at least, that's the finding of one Japanese research group.  The "poems" mentioned in this article are extremely brief,  so perhaps they lost something in the translation.  Loo 'ku, anyone?
