The blue economy refers to the sustainable use of ocean and marine resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystems. It includes activities such as fishing, maritime transport, offshore energy, tourism, and marine biotechnology. The concept emphasizes balancing economic development with environmental sustainability. For countries like Bangladesh, which has a vast maritime area in the Bay of Bengal, the blue economy offers immense potential to boost the national economy, reduce poverty, and create employment opportunities. Proper management, technological support, and international cooperation are essential to unlocking the full benefits of the blue economy.
