Pioneer of agroecology, Pierre Rabhi leaned on land chosen for its beauty despite its apparent aridity. Philosopher by the need to understand the impact of its Muslim and Christian cultures, Pierre Rabhi has learned of this internal conflict, as the barren land, a wealth that makes us share. Adept of the adequacy of speech and action, he tells us his fears, in my opinion based on the ineptitude of the hyper consumption myth of unlimited growth in a closed space, it was apparently inexhaustible: our mother planet. Zealot of voluntary simplicity, it exposes us how inner wealth, once issued by Human satiety of his basic needs, is how much more liberating than the dummy model to Western society in which the world hastens to try to adopt lapparente opulence. Apostle of non-violence, that wise allows us to glimpse a path to return to the essential human way in which civil society has started to take hold. Spread the sower. For us to act.
