DON GET RID OF THEM! the enrich the soil and have a major role to play in the natural world. they decompose the dead bodies of other organisms and dead plants. it then turns into compost, where then it becomes GREAT to plant plants in, due to the nutrients the soil has gained from the dead lifefourms. even if u r not an envoiornmentalist, and don't care aboue the earth, soil is connected to EVERYTHING! example: if u kill the earthworms, the soil wont be as nauturaly rich, so u put fertilifers on it. the soil is poor and the fertilizers mix with the soil, and because the soil is not healthey enought to stay in one place, it runs down hill until it reaches the lake. there, it settles and creates major problems to the city and environment it is in. it causes sediment and water pollution, and to get the sediment out, ( sediment is when soil runs downhill into a river and sits. this causes many other bad things to happen.) the city has to dredge it out, which costs thousand of dollars.
