CATDOLL : CATDOLL: What impact do earthworms have on the environment?

Earthworms dig holes to loosen the soil, decompose organic matter, and create good conditions for the growth and reproduction of soil microorganisms. They play a special role in soil improvement, pollution elimination, ecological environment protection, material circulation, and biodiversity. Many countries currently use earthworms to treat domestic garbage, organic waste, and purify sewage.

Earthworms contribute to the material circulation and energy transfer of soil processes through activities such as feeding, digestion, excretion (worm castings), secretion (mucus) and burrowing. They are one of the soil invertebrate groups (mainly earthworms, mites and ants) that have an important influence on multiple processes that determine soil fertility and are called "ecosystem engineers."
