Greenworld vol1

Greenworld is a hypothetical Earth-like exoplanet with a diverse and thriving biosphere. All animal-analogous organisms on Greenworld are descended from a radially symmetrical six-legged starfish-like animal. Animals on Greenworld secondarily developed bilateral symmetry (which is what is seen in most animals on Earth), developing into two major groups; “sulcosyms” in which the plane of symmetry lies between the legs (meaning they have three pairs of limbs) and “brachiosyms” in which the plane of symmetry has led to the formation of one “arm” at each of its ends (meaning two pairs of limbs and two unpaired limbs, one at the front and one at the back).

In the book, humanity discovers Greenworld just as Earth finally collapses under the pressure of mankind's impact and a generation ship with ten thousand people is sent to colonize the planet. Greenworld then explores the first thousand years of human colonisation on the planet through following some key families of settlers.Over the course of this timespan, every ecological catastrophe caused by humans on Earth is repeated on Greenworld. The book is divided into several shorter chapters, each telling a short story and featuring illustrations of the local animals and their interactions and relations to humans. Illustrations also include “excerpts” of advertisements, science papers, field guides and recipes. By the end of the book, Greenworld and its ecosystems are in ruins, mankind having caused a mass extinction event through their actions on the planet.
