The BlueCube represents the Blue Ocean Economy that should fit into the BlueCube when sustainable.The Blue Economy concept seeks to promote economic growth, social inclusion, and the preservation or improvement of livelihoods while at the same time ensuring environmental sustainability of the oceans and coastal areas.
At its core, socioeconomic development arising from oceans-related sectors and activities,  is separated from environmental and ecosystem degradation. The sustainable management of ocean resources requires collaboration across nation-states and across the public-private sectors, at a global scale (World Bank, 2017). So a clear blue-colored cube is our ideal goal.
