The Nordic Region shall continue to develop its co-operation around in relation to maritime environments. Important matters requiring Nordic co-operation include, among other things, international negotiations and processes, the preservation and restoration of marine life in the face of changing marine climates, the development of knowledge, environmental and climate monitoring, a sustainable blue economy and an ecosystem-based approach to planning and management. Eutrophication, ocean acidification, environmental pollution, waste including plastic, overfishing and invasive foreign species are all challenges which will require collaboration and the exchange of information if we are to attain a positive development. Sustainable fishing is also a prerequisite not just in terms of retaining the diversity of existing ecosystems, but also in terms of making sure that future generations will be able to continue to use fish stocks as a source of income.
