Book excerpt: The beauty and drama of a world beneath the surface of the waves This book brings alive the richly diverse world of an underwater paradise: the Mesoamerican Barrier Reef. Stretching 625 miles through the Caribbean Sea along the coasts of Mexico, Belize, Guatemala, and Honduras, this reef is the second largest coral structure on the planet. Imperiled Reef searches out the breathtaking intricacies of this endangered ecological treasure. Research shows that the future of the reef is at risk, Sheehy explains. Looking closely at threats ranging from global warming to overfishing to irresponsible development, Sheehy draws attention to the inspiring efforts of nongovernmental agencies, scientists, and local communities who are working together to address these challenges. She includes practical actions individuals can take to protect this reef—as well as marine ecosystems everywhere. Celebrating a vast, submerged landscape that has too often been undervalued, Imperiled Reef is both a strong case for protecting an international marvel and a powerful message of hope for the world’s oceans.
