It discusses the importance of natural disasters, threats, and risks from the lack of environmental sustainability and injustice, and land-use degradation patterns. It also addresses the question of how this combination of factors, in the context of still strong colonial policies, legacies and environmental injustice, has resulted in the increased degradation of coastal ecosystems and in increasing the vulnerability of both ecosystems and human communities to threats by climate change. Factors such as hurricane impacts, deforestation, air and water pollution, water scarcity, lack of food security and sovereignty, overfishing, and sea surface warming trends, massive coral bleaching, and mass coral mortalities are also addressed in the context of rapidly declining ecosystem and infrastructure resilience across the region. A conceptual model of potential climate change impacts is presented based on coastal ecosystems to provide a clear sense of the ecosystem trajectories, turning points, factors, and current issues confronting ecosystems and environments across the Wider Caribbean region.},
