Interesting Hypothesis in Somewhat Convoluted Form, May 17, 2000
This review is from: Gaia: A New Look at Life on Earth (Paperback)
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, September 10, 1997
This review is from: Gaia: A New Look at Life on Earth (Paperback)
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

4.0 out of 5 stars
Brilliant hypothesis, poorly presented, October 26, 2005
In essence, Lovelock says that since evolution started eons ago, all forms of life evolved together resulting not only in balance among themselves and their surroundings, but also in such a way that they regulate the environment, controlling the atmosphere, the salinity of the seas and the temperature. This complex eco-system is presumably an inevitable consequence of the algorithm of evolution running successfully. Want to know if there is life on another planet? Easy, look at the atmosphere.
This comes out in the book, but it is a bit bizarre. Lovelock seems to go from anthropomorphism (the world learning to breath and making decisions) to using scientific terms that the average non-science reader will have to look up. He presents a table on page 63 that I think is incomprehensible unless you understood the work that went into it, which is not presented. He finishes with a plea not to hunt whales, which seems like a strange non-sequester to the book as whole.
As a consequence of this he seems to have appealed to crystal-swinging, horoscope-reading new age wo-wos rather than hard scientists. This is a shame, because the idea is brilliant (thus 4-stars), and could result in decades of research, added to which Gaia is a great name. It seems self-evident that we are part of and completely dependent upon the environment around us. Lovelock has such faith in the self-regulating mechanisms, he rather pooh poohs our ability to mess with it too much. However, it seems to me that evolution and balance takes time - we do things incredibly fast - our ability to warm the globe has only been for a couple of hundred years. We could easily give Gaia a fever, by overcoming her ability to make gentle regulations. If this happens, we do not know what the results will be, but we almost certainly will not benefit from them. As they say; "nature bats last".
Everyone should read this book and, despite its faults, it is readable.
