After children in Argentina are done reading Mi Papá Estuvo en la Selva (My Father Was In the Jungle), they can plant the entire book in the ground and watch as it grows into a tree. The book, intended for children between 8 and 12 years old, is narrated by a young boy telling the story of his father's adventures in the Ecuadorian jungle.

The book is the first in an initiative called Tree Book Tree launched by Pequeno Editor, a children’s book publisher in Argentina, in concert with FCB Buenos Aires. The aim: provide an elegant demonstration of how paper products can impact the environment. The tome is handmade using acid-free paper, ecological ink, and jacaranda seeds that sprout when planted. Bookstores around Argentina are displaying Mi Papá Estuvo en la Selva already planted and germinating in store windows.
