What problems do earthworms cause?

The worms alter the physical and chemical properties of soils, changing the pH, nutrient and water cycles, and disrupting symbiotic relationships between soil fungi and roots (mycorrhizas).

Can earthworms cause damage?

Studies have found earthworm activity can reduce both the total coverage and the diversity of plant species among the understory canopy by between 25 and 75 percent [source: University of Minnesota]. This effect ripples up the food chain to affect deer and other vertebrates that depend on that vegetation for food.

However, this is still much lower than the eutrophication caused by open dumping of untreated manure.

What is vermicomposting What are the advantages and disadvantages of vermicomposting?

Vermicompost has a plethora of benefits, most importantly as follows: (1) it acts as biofertilizers, restores soil nutrients, stabilizes soil, and enhances soil fertility at a long-term period; (2) it attends to social issues and recycles waste; and (3) it is shown to be a profitable enterprise as a circular economy.
