It has taken all humankind until Mr. Lovelock, before someone has had the insight, in an eureka moment, to understand how our precious planet really works. We are privileged to benefit from his pluridisciplinar background and independence of thought. The breakthrough laid down in this one book, in a very entertaining style, is only comparable to a handful of stellar moments in the history of humankind: our planet is suitable for life, precisely because all forms of life ceasessly toil to render it habitable. Go ahead, change forever the way you look at the world and your assessment of you place and role on it.
