Abstract:
Climate change poses significant threats to biodiversity in coastal ecosystems, resulting in habitat degradation, species migration, population declines, and reduced ecosystem services. This study examines the impacts of rising sea levels, ocean acidification, and temperature fluctuations on mangroves, coral reefs, and seagrass meadows, which serve as critical habitats for marine and coastal species. Key findings reveal substantial habitat loss, biodiversity shifts, and a decline in vital services such as carbon sequestration, fisheries productivity, and natural storm protection. The study highlights the socio-economic consequences for coastal communities and underscores the urgency of implementing restoration efforts, expanding marine protected areas, and adopting sustainable resource management practices. While limitations such as data constraints and geographic scope were identified, this research provides actionable recommendations to mitigate the adverse effects of climate change. The findings contribute to the growing body of knowledge on the ecological and socio-economic impacts of climate change, advocating for immediate and collaborative global action to preserve coastal ecosystems.
