The soil decomposition cycle and the water cycle are two of the many kinds of cycles that occur in the natural world. But nature can use some help in these environmentally stressful times, so after describing the way in which the soil and water cycles work, author Michael Elsohn Ross also offers an illustrated description of what young people can do to recycle natural and human-made materials.
