To coincide with Earth Month, Penn State University Geology professor Richard Alley has released the book Earth: The Operators’ Manual (W. W. Norton & Company, 479pgs) as a companion the the two-part PBS special of the same name that aired earlier in April. The author, who also hosts the television program, addresses the issues of climate change and renewable energy in an engaging, interesting way, and uses scientific research to dispel the myths propagated by those who deny global warming. Outlining man’s reliance on fuel throughout history, the Nobel Peace Prize winner utilizes scientific findings to show how our current hyper-consumption of fossil fuels is harming the environment and contributing to the greenhouse effect. Though tackling a serious subject, Alley, A former member of the UN climate change committee keeps the tone optimistic by suggesting solutions to the climate change problem using alternative energy sources like solar, geothermal and wind. He feels that today’s technology makes tapping into these resources a feasible option in healing the environment, and will thus stimulate economic growth and create a significant number of new jobs.

Even the little ones can celebrate Earth Month and gain environmental awareness with the Dr. Seuss classic The Lorax (Random House Books for Young Readers, 72pgs). Originally published in 1971, this delightful picture book carries an eco-friendly message that is just a relevant today. Using his characteristic whimsical rhymes, Dr. Seuss tells the story of the callous Once-ler who ruins a beautiful place by cutting down all the Truffula Trees in order to manufacture cheaply made Thneeds. The furry Lorax repeatedly warns the Once-ler of the damage he is doing to his home, but even he is eventually driven away by the environmental devastation, leaving behind only a rock engraved with a wish for a better future. Yet, the book ends with a kernel of optimism. The regretful Once-ler, now living in a barren wasteland, has saved one seed from the Truffula Tree, in hopes that a warm-hearted child will nurture in a new era that is green and healthy.
