Our Earth is more than just the place we live—it’s a living, breathing, awe-inspiring system that supports all of life as we know it. From the tallest mountains to the deepest oceans, from the icy Arctic to lush rainforests, Earth is filled with beauty, mystery, and a complex web of life in which we are a vital part. Every animal, plant, river, forest, and cloud plays a role in keeping our planet balanced and alive. And yet, despite this natural harmony, our Earth is facing growing dangers—dangers largely caused by us, by human activity, habits, and decisions made over time.

Stretching more than 2,300 kilometres along Australia’s northeast coast, the Great Barrier Reef is the largest living structure on Earth—and one of the most extraordinary ecosystems our planet has ever known.

But while its scale and splendour inspire awe, its delicate balance hangs by a thread.

This book is a journey into the remarkable world of bees, exploring their hidden importance and why our future is so closely tied to theirs.

When most people hear the word “fungi,” they think of mushrooms — the whimsical toadstools that pop up after rain, the champignons in our kitchens, or the button mushrooms scattered on a pizza.

They are living fossils whose epic migrations link the distant past with our uncertain present, journeys written in sand, salt, and instinct.
