       | "If you live in an area of North America where the glaciers once
       | rested, there are no native terrestrial worms in your region. All
       | of North America's native worm populations reside in the
       | southeast and the Pacific northwest. All other worms species were
       | wiped out by the glaciers. This means that, for millennia,
       | northern North America's native ecosystems have evolved without
       | the influence of any type of worms in the soil.
       | 
       | When Europeans settled the continent, they brought with them
       | earthworms, specifically those known as night crawlers and red
       | wigglers, in the ballasts of their ships. Since then, these worms
       | have been spread all over the continent by a wide range of human
       | activities like farming, composting, and fishing. Since their
       | introduction, many forests have been invaded by these annelids
       | and are now suffering heavily from earthworm activities."
