How are earthworms important to Humans?

Of particular importance to people is the underground tunneling of earthworms through soil. Earthworm passageways open up soil pore space for air and water. Adequate water space is needed for good infiltration and percolation of water through soil. It improves drainage, and therefore discourages the waterlogging that can set the scene for fungal diseases and root rot. Earthworm death and decomposition adds organic matter to soil. Healthy soil needs both organic matter, and air and water pore space. So earthworms meet both needs.
