As the nations of the Caribbean respond to and prepare for climate change, tourism has the potential to both worsen and mitigate these effects. In this book we look at marine tourism and its connection with ocean health, fisheries, and critical ecosystems, including coral reefs. We consider the role that marine protected areas can play in preserving reefs and other ecosystems, leading to greater resilience in the face of climate change. Finally, we look at how the tourism industry is responding to the threat of climate change, using its economic and social capital to foster positive change in the Caribbean and other parts of the world. While the situation is clearly urgent, we hope this volume provides readers with some optimism, as well as tangible ideas for using tourism to help mitigate the impending effects of climate change on marine ecosystems and economies.
