The Gaia theory is based on the premiss that the Earth is poised to reproduce. Experiments are showing that sustainable mini-biospheres are a possibility - complete ecological systems in which life is possible. The author argues that it is time we stopped thinking of ourselves as a super-species. Human beings and all our inventions are just part of nature, helping the Earth to produce new species. In this book the author pioneers biospherical experiments giving us a glimpse into the future not just of our species but of the planet as a whole.
