" Any environment, any single life is in a continuous state of change. This is just more obvious when you pay attention to earthworms. Their work may seem unspectacular at first. They don't chirp or sing, they don't gallop or soar, they don't hunt or make tools or write books. But they do something just as powerful: they consume, they transform, they change the earth. "
