We venture into the inner spaces of the earth to explore her mysteries, rekindle wonder. As we cross the threshold into the underland, following our own Cerunnos, our knowledgeable guide, we find ourselves within an adventure in which space and time change at every step, climbing, descending, grasping onto crevices and cracks to move ahead and discover the possibilities that hide right under our feet. We also go further into the life story of the owner of the Rio Claro Reserve and listen to his words and wisdom regarding the issues of the Magdalena River, so intertwined with the history of Colombia, as revealed in the new Wade Davis book. I conclude with the emergence of the new face of the Green Human, the newest  earthlings who will be tasked with re-building a radically different, nature-centric future.
