The book adopts a fact-based approach, offering a comprehensive overview of island formation, biogeography, and political history. It reveals how these seemingly remote locations are crucial microcosms reflecting broader planetary processes. Islands are not only places of natural beauty, but also arenas of complex international affairs.
The book progresses through three sections: defining the unbelievable island, detailed case studies of toxic environments and contested territories, and analysis of islands where recent discoveries have altered geographical knowledge. Ultimately, Unbelievable Island Facts demonstrates the importance of understanding these isolated systems for a more nuanced view of global challenges in Earth science, travel, and geography.
