Hundreds of species of marine life are facing mass extinction as pollution, climate change and overfishing threaten to create a catastrophe “unprecedented in human history”, according to the latest report by the International Programme on the State of the Ocean (IPSO) and the International Union for the Conservation of Nature (IUCN).
''The findings are shocking,'' said marine biologist and scientific director of IPSO, Alex Rogers. ''We are looking at consequences for humankind that will impact in our lifetime and, worse, our children's and generations beyond that.''
Some of the key scientific conclusions in the report include:
1. Human actions have resulted in warming and acidification of the oceans and are now causing increased hypoxia
2. The speeds of many negative changes to the ocean are near to or are tracking the worst-case scenarios from IPCC and other predictions
3. Resilience of the ocean to climate change impacts is severely compromised by the other stressors from human activities, including fisheries, pollution and habitat destruction.
4. Ecosystem collapse is occurring as a result of both current and emerging stressors.

According to the report, overfishing alone has reduced commercial fish stocks and by-catch species by more than 90 percent.
The global fishing industry generates US$246 billion a year but faces annual losses of over US$36 billion if current conditions persist.
According to Dr. Rashid Sumaila, director of the Fisheries Economics Research Unit at the University of British Columbia Fishery Centre, “Fish contribute significantly to global well-being through revenues, jobs and through household incomes.
"If you consider what the fish pump into an economy through processing, the restaurants and even agriculture, it's much more than just the landed value."

Overfishing may be just one of the many problems that the world’s oceans currently face, but it is perhaps the easiest for governments and societies to solve.
With a traumatic implosion – economic, financial, political, and social – now taking place in Greece, we should expect heated debate about who is to blame for the country's deepening misery. There are four suspects – all of them involved in the spectacular boom that preceded what will prove to be an even more remarkable bust.
