Marine ecosystems provide valuable services to people, like food, carbon storage, and tourism opportunities. However, human activities are putting pressure on these ecosystems, leading to degradation and loss of biodiversity. To protect these benefits, it is important to manage marine resources sustainably. Scientists are studying different ways to assess and map these ecosystem services to help policymakers make informed decisions. The main focus is on understanding the types of services provided by marine ecosystems, how they are being affected by human actions, and how to incorporate this information into decision-making processes.
