The burrows not only help with water drainage and filtration, but they also create airways that help with soil aeration. This physical alteration means that water and soluble nutrients can travel more easily down to the plant roots. The way some worms tunnel also helps to move fertilizer applications below soil where they can be utilized by the plants more effectively.

Charles Darwin was famously enthralled by earthworms, and stated: It may be doubted whether there are many other animals that have played so important a part in the history of the world, as have these lowly organized creatures. In fact, Darwins final publication in 1881 was a book about worms, entitled The Formation of Vegetable Mould Through the Action of Worms. The underside was described as being a flesh-red that darkened into grey when placed in spirit for preservation[13]. There are three categories that earthworms fall into, and these can be defined by that part of the environment the worm predominantly inhabits.
