★ A surprising way to think about time, through the lifespan of everyday trash
We throw things away and never think about them again. But a plastic cup, a bus ticket, a piece of gum – they all have their own timelines, often longer than our own lives. This book transforms the abstract concept of "degradation time" into something children can see, compare, and understand. It makes invisible waste visible again.
★ From an award-winning author with a global audience
Davide Calì is one of Europe's most celebrated children's authors, with over 100 books translated into more than 30 languages. His works are beloved by children and parents alike – and this book is no exception. It brings his signature blend of curiosity, gentle humour, and thoughtful storytelling to a topic that concerns every one of us.
★ Awareness without alarm, a calm conversation about a big topic
This is not a book that scolds or terrifies. It doesn't say "the world is ending." Instead, it invites children (and adults) to look at everyday objects with fresh eyes – to ask where things go when we throw them away, and how long they stay there. A quiet, powerful way to start a conversation about sustainability, one napkin at a time.

A napkin takes three months to fully degrade in nature. A bus ticket takes twelve months. A piece of chewing gum takes five years. A cigarette end takes ten years. What do these numbers really mean?

This book helps young readers understand the hidden timeline of everyday objects – and, in doing so, learn to think about time, waste, and our relationship with the planet.

The author also conducts workshops in schools, bookstores, and libraries, where he teaches children about degradation time and what we can do for the future. But this is not a book of blame or doom. It is a gentle invitation to awareness – because our world is not destroyed yet.

About the Author
Davide Calì was born in 1973 and is a celebrated Italian children's author and illustrator. For him, writing stories is like writing letters to friends he has never met – and then waiting, with anticipation, for their reply. He began his creative career writing plays, acting, and composing music, and his storytelling talent found its fullest expression in 2005 with the publication of his picture book I Wait..., which won the Golden Baobab Prize (Grand Prix of the French publishing market). Since then, he has published over 100 books, many of which – including Piano Piano, Marilyn the Great Whale, Invincible Iron Mama, and Tailor-made Dad – have become international bestsellers. His work has been translated into more than 30 languages and recognised with numerous awards across Europe, Asia, and the Americas.
