The ambition of this book is to suggest a radically new theory on economy: the symbiotic economy. This new economy would allow human beings and ecosystems to live together in harmony. Isabelle Delannoy offers a combination of the different technics and researches of the past few years, like permaculture, private sharing or circular economy for example. By associating the benefits and the common principles of these concepts, she realized we could improve our way of using matters while developing the producing capacities of the soil. The symbiotic economy is based on the symbiosis between human intelligence, the power of natural ecosystems and the technosphere. Finding the good balance between these three elements would make it possible for us to produce without draining the resources, but rather by renewing them.
