Animals can change the earth in many ways. A common and easily observed manner is by earth worm castes, The worms ingest loamy (organic rich) soil as they burrow and pass it through their digestive system and later pass off the soil minus what they have extracted for their needs as little piles of about 1/8th inch balls of soil. Over a period of several hundred years they can cover an acre of soil with new and mineral rich deposits which will become part of the new top soil.
