Worms, WORMS, WORMS! Sad but true—those lowly, wriggling saints of the natural world, hailed as creators and saviors of the soil since the days of Charles Darwin, are now known to represent an Evil Empire.
Well, maybe not evil. But it turns out that most North American earthworms were introduced from other continents, and the new arrivals, while doing some good in gardens, actually disrupt the ecology of forests, diminish the rich fabric of life in the soil, and even contribute to global warming.
