The Biosphere

This edition - complete with extensive annotations, an introductory essay placing the work in its historical context and explaining its relevance to readers today, and a foreword cosigned by a stellar group of international experts - will be the definitive edition of this classic work. --Lynn Margulis This classic 1926 book is the first sustained expression of the idea, now widely accepted, that life is a geological force. It founded the field of biogeochemistry and is one of the seminal works in what is now known as Gaia theory. This edition, the first unexpurgated English translation, is fully annotated for the modern reader.
