Human activities are taking a terrible toll on the world's oceans and seas. That's what Secretary-General Ban Ki-moon says in a message marking World Oceans Day, being observed Monday 8 June.

He says vulnerable marine ecosystems, such as corals, and important fisheries are being damaged by over-exploitation, illegal, unreported and unregulated fishing, destructive fishing practices, invasive alien species and marine pollution, especially from land-based sources.

He adds that increased sea temperatures, sea-level rise and ocean acidification caused by climate change pose a further threat to marine life, coastal and island communities and national economies.

Secretary-General Ban says the first observance of World Oceans Day allows all to highlight the many ways in which oceans contribute to society.

He says it is also an opportunity to recognize the considerable challenges the international community faces in maintaining the capacity to regulate the global climate, supply essential ecosystem services and provide sustainable livelihoods and safe recreation.

The theme of World Oceans Day, "Our oceans, our responsibility", emphasizes our individual and collective duty to protect the marine environment and carefully manage its resources.

The Secretary-General says safe, healthy and productive seas and oceans are integral to human well-being, economic security and sustainable development.
