Talk about the relationship between earthworms and humans

Earthworms are decomposers. For humans, they can decompose the organic waste produced by humans and turn it into inorganic matter for use by plants and others. Therefore, if there are earthworms in the yard, vegetables or flowers will grow better... At the same time, human activities will provide earthworms with a certain source of energy, such as food. However, human pollution of soil and water will cause great harm to the living environment of earthworms and threaten their lives.
