Marine protected areas are established mainly to:

Marine protected areas (MPAs) are designated regions in the ocean where human activities are regulated to preserve the natural environment and biodiversity. The primary goal of these protected areas is to safeguard marine ecosystems from overfishing, pollution, habitat destruction, and other threats that can lead to the decline of marine species and habitats. By providing a safe haven for marine life, MPAs help to sustain biodiversity, allowing various species to thrive and ecosystems to remain healthy.

While promoting tourism and recreational diving can be secondary benefits of MPAs, their main purpose is focused on conservation and preservation of marine environments. Therefore, establishing MPAs is crucial for maintaining the resilience of marine ecosystems, enhancing their ability to adapt to changes and stresses, and ensuring that future generations can enjoy the benefits of healthy oceans.
