What do humans use worm feces for?

Worm feces are a great fertilizer. People sometimes put worms in their yards or compost boxes. Worms can eat things that people don't want, such as old vegetables. When the worms eat this and defecate, their feces is filled with good nutrients for the soil. Then people spread the feces (which looks much like soil) over their gardens so the plants can get these valuable nutrients.
