Worms are cute.
But they poot.
Turns out trendy vermicomposting — setting up a bin on your balcony or in your yard, filling it with shredded paper, kitchen scraps and red worms, and then collecting the "castings" (worm poo) to use as fertilizer — may be creating greenhouse gasses.
Darn. Such a nifty idea. Wiggly red worms you buy at a bait shop or nature store. No need to run the garbage disposal. Less dumping onto the landfill.
But now we learn what the little buggers are emitting as a natural byproduct of digestion: nitrous oxide, way more powerful than carbon dioxide.
Odds are the average home worm bin is not contributing huge loads of the bad gas. So you probably shouldn't feel guilty about continuing your project for now.
It's not easy being green.
