The book "The Unknown Encyclopedia" by Serenella Quarello, Alessio Alcini

This book is a fascinating journey that introduces us to extinct or endangered species. This journey will help us understand what we can do to ensure that no part of life or species is lost. Even the most unknown animals make our planet richer and more beautiful. Each has its own justification for its existence, and their loss would be irreversible. The author introduces us to the stories of known and unknown species: Martha's pigeon and George's snail, the dodo, the Tasmanian wolf, and even the recently discovered Starry Night frog. The book is intended for readers aged 6 to 9.
