Portugal has established the largest Marine Protected Area network in Europe, covering 287,000 square kilometers around the Azores. This initiative aims to protect unique underwater ecosystems and marine species from harmful activities. José Manuel Bolieiro, President of the Azores, emphasizes the importance of this achievement for global marine conservation. While MPAs can enhance marine biodiversity, effective enforcement is crucial, and challenges like pollution and climate change remain. The Azores' efforts may inspire other regions to contribute to the global goal of protecting 30% of land and ocean by 2030.
