The Earthworm Ambulance roams through the cityscape, collecting earthworms that are unable to find their way back into the soil. The ambulance searches for an adequate new habitat for the disoriented worms. Earthworms are - among others - indispensable organisms for soil formation, likewise, their numbers are an indicator of soil quality.
