Worms are on the move, and people are nervous.
That’s because they’re taking over territory in the Far North that’s been wormless since the last ice age.
Scientists say the expansion will inevitably change northern ecosystems, with implications for the whole planet, in ways we don’t fully understand and probably can’t undo.
Earthworms actively contribute to soil health by munching on decaying organic matter and pooping out nutrient-rich fertilizer.
But that means worms also have the potential to upend the natural balance of ecosystems in Arctic and sub-Arctic zones.
