Biodiversity is under great threat as a result of the effects of climate change and global warming. Therefore, the ocean economy and the marine economy are among the economies that will be most affected by the effects of climate change. Each change in ocean and sea levels causes changes in biodiversity. Considering its importance in terms of food health, economic and social development, the sustainability of the marine economy is an important issue. The aim of this study is to present indicators of ocean economy among OECD countries and show the importance of ocean and marine economy in the long term. © 2023, IGI Global.en10.4018/978-1-6684-8879-9.ch012info:eu-repo/semantics/closedAccessBook Chapter2122322-s2.0-85168070135
