Healthy seas and coasts would pay healthy dividends in a green economy, according to a report released by the United Nations Environment Programme (UNEP) and partners that highlights the huge potential for economic growth and poverty eradication from well-managed marine sectors. The report, Green Economy in a Blue World, argues that the ecological health and economic productivity of marine and coastal ecosystems, which are currently in decline around the globe, can be boosted by shifting to a more sustainable economic paradigm that taps their natural potential - from generating renewable energy and promoting eco-tourism, to sustainable fisheries and transport.
