Protected marine areas are designated regions in oceans and seas where human activities are restricted to conserve marine ecosystems and biodiversity. These areas help safeguard habitats for various species, including fish, corals, and marine mammals, allowing them to thrive without the pressures of overfishing, pollution, or habitat destruction. By establishing marine protected areas (MPAs), governments and organizations aim to restore and maintain healthy ocean environments. MPAs can vary in their level of protection, with some allowing limited activities like recreational fishing while others prohibit all human activities. Overall, these areas play a crucial role in sustaining the health of our oceans.
