The Antarctic and Southern Ocean Coalition (ASOC) is calling on global leaders to take action at a key meeting in South Korea to protect the Antarctic Peninsula and manage the krill fishery, essential for the region's biodiversity. The meeting, involving the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), aims to establish a marine protected area (MPA) in the Antarctic Peninsula to preserve habitats for species like emperor penguins and blue whales. Additionally, the article underscores the importance of MPAs in the Southern Ocean for carbon sequestration and biodiversity protection, advocating for large-scale MPAs to meet the global 30×30 target of protecting 30% of the ocean by 2030.
