Book Reviews of Gaia: A New Look at Life on Earth

Book Review: Imagine an organism as big as Earth!
Summary: 5 Stars

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.
