Coral reefs face a multitude of threats beyond climate change, including overfishing, destructive fishing practices, pollution from land-based sources, and unsustainable coastal development. Addressing these local pressures is essential for the health of these reefs, and it often requires collaborative efforts between scientists, policymakers, and local stakeholders. Furthermore, it's essential to recognize the interconnectedness of coral reefs and local communities. In many parts of the Global South, coastal populations rely on these reefs for sustenance, livelihoods, and cultural significance. Engaging local communities in conservation initiatives is not only a matter of social responsibility but also a practical necessity for long-term reef resilience.
