‘Guide’ helps us to relate to our planet

Some regard humanity as the most intelligent species and therefore the masters of the world.

We are entitled to harvest the Earth’s resources to meet our wants or desires. A larger number see humans as stewards of the Earth. We are to use the Earth resources carefully, particularly with regards to the needs of future generations.

A recent book on the Earth and humanity is “Earth: A Tenant’s Guide,” written by Frank H.T. Rhodes, a President Emeritus of Cornell. Rhodes is a geologist whose previous books include “The Evolution of Life.” “The Language of the Earth” and “The Creation of the Future: The Role of the American University.”

“Earth: A Tenant’s Guide” has ISBN of 978-0-8014-78239-9 (paperback, 377 pages and about $24).

Rhodes quotes a native American proverb, “We don’t inherit the Earth from our parents; we borrow it from our children.” This idea gives an insight into the different perspective that “Tenant’s Guide” is based on.

“Tenant’s Guide” is divided into three segments: 1. The Present Earth, 2. Earth in Past, 3. Future Earth – the Sustainable Planet. Each segment is largely self contained and can be read on its own.

Dr. Rhodes opens “The Present Earth” with series of chapters on How Can One View the Earth: The Third Planet, Our Home Planet, The Rocky Planet, the Blue Planet, The Veiled Planet, The Hazardous Planet, The Ancient Planet, the Bountiful Planet and The Finite Planet.

The “Earth in Past” includes The Uninhabitable Planet, The Living Planet (History of Life’s Development), The Warming Planet (Inconstancy of Climate), The Polluted Planet and The Crowded Planet.

“Future Earth: Sustainable Planet” includes the chapters: The Sustainable Planet, Water as Sustenance, Air as Sustenance, Soil as Sustenance, Food as Sustenance, Energy as Sustenance (Reviews fossil fuels and renewable energies), Materials as Sustenance, Prospects for Sustenance, and Policies for Sustenance.

“Earth: A Tenant’s Guide” gives an objective view of the key aspects of Earth and the impact of humanity. It’s illustrations are drawn from a number of recent key texts in geology, paleontology and biology.

“Tenant’s Guide” avoids taking one sided positions (environmental doomsday or ignoring the consequences of human activities). The issues discussed show how the Earth’s diverse systems interact, not always smoothly.

The Earth is our only home; moving elsewhere (like Mars) is not an option.

This columnist will be using “Earth: A Tenant’s Guide” as a text in a junior interdisciplinary course at Frostburg State.

SKY SIGHTS AHEAD: The evening moon will appear near the bright planet Jupiter tomorrow evening . On Wednesday, the planet Venus will be at her brightest in the eastern dawn. The evening moon grows to full on Feb. 14, appearing near the sickle of Leo.

  • It’s hotter here than in D.C. or Baltimore

    At this time of the year, the weather is a frequent subject of conversation, particularly the temperatures. We are now in the “Dog Days,” usually the hottest days of the year. The term comes from our sun appearing to be near the “Dog Star” (Sirius) and the “Little Dog Star” (Procyon). In reality, the sun is now about 94.5 million miles away while Sirius is 8.6 light years away with Procyon at 11 light years distance. Sunlight takes only 507 seconds to reach us, while the two dog stars’ light takes about a decade to travel to our eyes. So our sun is in the same direction (but not distance) as these two bright winter evening stars.

  • Fronts, highs, lows determine weather

    Weather news on television and internet focus on violent weather, extreme temperatures and flooding.

  • A long and winding road faces our food

    Last week’s column dealt with organs you can do without, our DNA (molecular blueprint for our bodies) and hair. My reference is “Body: Discover What’s Beneath Your Skin,” a Miles Kelly Book, written by John Farndon and Nicki Lampon and published in 2010. This column will consider finger and toe nails, breathing and coughing, saliva, mucus and your food’s long and torturous journey. Most cities and mid sized towns have nail shops where you can have your finger nails and toe nails adorned. Nail painting can be traced back 5,000 years.

  • Here’s a look at what goes on inside you

    In high school, my favorite science course was biology. I can remember Mr. Munley in his wheelchair. Our class went on a field trip to the University of Miami Medical School where we saw the cadavers used by the medical students.

  • Moon-watching easy when you know how

    Long before the first writing (scratches on clay tablets) appeared, our early ancestors noticed that the moon went through a regular cycle of shapes in about 30 days.

  • Here’s how you can tell the stars, planets

    How can one tell one star from another at night? It’s a matter of knowing the sky areas (constellations).

  • Smithsonian guide to stars is a good one

    At a local book store, I yielded to temptation and bought “Stars and Planets,” a Smithsonian Nature Guide written by four authors. Dinwoodie, Gater, Sparrow and Stott. It’s another Dorling Kindersley product with ISBN 978-0-7566-9040-3 and a 2012 copyright. “Stars and Planets” is a trade size paperback that is beautifully illustrated with appealing diagrams. “Stars and Planets” begins with the biggest topic, the Universe. There is a striking visual showing the known universe on the hugest scale, a delicate lacework of superclusters of galaxies with large voids. It resembles a bubble bath!

  • Think a little more and be less frazzled

    Last Sunday’s column dealt with using technology carefully in education. What about technology in everyday life? There is a marvelous book “The Thinking Life,” by P.M. Forni, of The Johns Hopkins University which addresses this issue as well as timeless suggestions for living by Greek and Roman thinkers. “The Thinking Life: How To Thrive in the Age of Distraction” was published by St. Martin’s Press in 2011 with ISBN 978-0-312-62571-9. Dr. Forni also wrote “Choosing Civility” and “The Civility Solution”.

  • Technology helps with learning, but take care

    Since I have been involved in teaching, two different technologies have been applied to learning at the secondary and collegiate level. The first was video (from videocassettes to DVDs) where a student or class might watch a presentation of some historical event, or a set of scientific principles or even a simulated exploration of the human body.

  • Here are numbers that apply in our lives

    One of the best exercises is walking. Cardiologists suggest that each of us walk 10,000 steps per day. Assume each step is 0.5 meters or 19.7 inches. Then 10,000 steps would cover 5,000 meters or 3.11 miles. But studies find that the average American (from age 4 and up) takes only 2,000 steps/day or 1 kilometer.
