This paper discusses how the earthworm is considered the environment's natural recycler since it turns dead animals and plants into useful fertilizer within the soil. It examines how many people and companies throughout the world now use worms as a natural way to make composite out of leaves and other organic materials and how scientists are studying these creatures in an effort to replenish nutrients in soil that has been ruined with chemical agents.

Conclusion
From the Paper:
"There are over 3,600 species of earthworms worldwide and many scientists believe twice that number may exist (McCarthy, 2002). One variety that lives near the Equator can grow to be 8 feet long and weigh over a pound. Nightcrawlers are different from most earthworms since they live deep in the soil and dig vertical tunnels over six feet deep. They also can grow to be a foot long and live over 5 years. Most earthworms live near the top of the soil, dig horizontal tunnels, and are short. Nightcrawlers do not need to completely leave their holes to feed. They keep their tails in their tunnels and bob back and forth looking for food and if grabbed by a predator, will hold on to the walls of their tunnels with amazing strength. At night, these worms can be heard as they rustle leaves while searching for food."
