Worms
Wormeries 'may add to greenhouse gases' | Earth News | Earth | Telegraph
Worms may not be as environmentally friendly as the growing number of gardeners who use them to help compost their kitchen scraps and grass clippings believe, say scientists.
In fact, the greenhouse gases emitted by a large commercial worm composting plant may be comparable to the global warming potential of a landfill site of the same scale, according to the Open University.
This is because worms used in composting emit nitrous oxide - a greenhouse gas 296 times more powerful, molecule for molecule, than carbon dioxide.

Mr Frederickson told Materials Recycling Week said: "Everybody loves worms because they think they can do no harm but they contribute to global warming.
....we must remember if we are evaluating this method against other ways of getting rid of wastes, such as landfill and incineration, that worm composting can also be a source of greenhouse gas emissions."
The worms crawl in and the worms crawl out
The ones that crawl in are lean and thin
The ones that crawl out are fat and stout
Your eyes fall in and your teeth fall out
Your brains come tumbling down your snout
Be merry my friends
Be merry
