Customer Reviews

We need to be good stewards of our planet!

I read this book sometime ago and is impacted me significantly as it has with many others. I enjoyed the explanation of the huge organism (Earth) that is self- regulating. I also enjoyed that Lovelock points out that we humans are part of the environment and belong here. We will produce waste. Having said that, any system can overload. Thus, we need to be good stewards of our planet. As the astronauts left the earth in the 1960's and headed towards the moon they looked back at our planet and did not see borders or countries. They saw the earth as a single unit...beautiful and fragile. It rotated on an invisible string in the blackness of night. It affected many of the astronauts profoundly. The book has already helped many more people see the earth as a single unit. If it can continue to do that, hopefully we will find a way to live more harmoniously with the environment on our planet. Gaia is a great read and a way of looking at things that is both fascination and enlightening! The Re-Discovery of Common Sense: A Guide to: The Lost Art of Critical Thinking

Imagine an organism as big as Earth!

Reading Edward Wilson's "The Future of Life" served as the spark to pick up and read this book. And its true, good things do come in small packages. The book is all of 140 pages, and is written in a lean, but not glossed-over style. Robert Lovelock (to my knowledge) is the contemporary father of the study of the earth as a complete living system. Lovelock readily admits that the book serves more to promote the dialog about our planet as a living, breathing whole and to share key discoveries that support his concept. (He states in the Preface that his follow-on book, "The Ages of Gaia" aims to build the scientific argument to the Gaia theory.) By no means, does Lovelock detour around the science that supports his case. With the scope of the topic requiring knowledge of both physical and biological science, and the small number of pages, he manages to instruct and create a sense of awe in a short amount of time.The 3 major principles he brings to light about Gaia are:1. Gaia exhibits a tendency to keep conditions (e.g., temperature, air quality) constant for all terrestrial life.2. Like other living systems, Gaia has vital organs at the core, and expandable or redundant ones on the periphery.3. Under the worse conditions, Gaia responses similar to other cybernetic systems (i.e., where time constant and loop gain are important)The material is far reaching in both its scope and in shaping our understanding of where we stand. Put in the context of Gaia, we have straddled ourselves to the largest of all known living and breathing creatures.

Interesting Hypothesis in Somewhat Convoluted Form

James Lovelock has created a powerful and interesting argument in this book that will keep scientists busy for centuries. He notices that there is an ability for the Earth to maintain relatively constant conditions in temperature, atmosphere, salinity and pH of the oceans, and reductions in pollutants that defies the simple observations of what "should" happen. From this, he concludes that there is a complex of physical, chemical and biological interrelationships that work like a living organism, which he defines as the Gaia Hypothesis. For defining that concept and providing some of the measurements to establish its premises, he deserves a 7 star rating.Unfortunately, the argument is expressed in overlong and convoluted fashion. He deliberately limits himself to a nonscientific explanation in this book. The scientific version of the argument is in The Ages of Gaia. Although the book is not long, it certainly could have been condensed into a longish article for Scientific American or The Atlantic Monthly. My second quibble is that the editor was nowhere in sight on the organization of the book. The key point is often buried in the third sentence of the last paragraph in a chapter. The argument in between wanders into all kinds of places where it doesn't need to go. For organization and editing, I give this book a one star rating.So the average is a 4 star rating. The writing itself is pleasant enough. Don't let the lack of organization and editing put you off, for it is worth your while to read this book. It will remind you of the benefits of the sort of sytems thinking that Peter Senge talks about in The Fifth Discipline. The other thing you will learn is the weakness of scientific work that fails to develop enough field data and to connect enough with other disciplines. I was struck by the same observations recently while visiting environmental scientists at the Smithsonian Institution. The basics in many of these areas have yet to be measured and evaluated. This book will point countless generations forward in understanding how our plant maintains its environment that permits life to flourish. Clearly, it is a stallbusting effort to replace "stalled" thinking about the history and future of the Earth. I found the key questions (such as why doesn't the ocean become more saline?) to be irresistible. I think you will, too. Enjoy and think!

How to change your outlook

Although parts of the text are confusing and too deep for a mere mortal like myself, this book changed the whole way I look at the earth and my own role upon it, not to mention the part my species is taking. Reading and re-reading yields great rewards, the arguments, whether agreed with or not, are cogent and thought provoking, and will provide for many a night spent in those deep discussions with friends
