'Shocking' state of seas threatens mass extinction, say marine experts. Overfishing and pollution putting fish, sharks and whales in extreme danger – with extinction 'inevitable', study finds

Fish, sharks, whales and other marine species are in imminent danger of an "unprecedented" and catastrophic extinction event at the hands of humankind, and are disappearing at a far faster rate than anyone had predicted, a study of the world's oceans has found.
Mass extinction of species will be "inevitable" if current trends continue, researchers said.
Overfishing, pollution, run-off of fertilisers from farming and the acidification of the seas caused by increasing carbon dioxide emissions are combining to put marine creatures in extreme danger, according to the report from the International Programme on the State of the Ocean (Ipso), prepared at the first international workshop to consider all of the cumulative stresses affecting the oceans at Oxford University.
The international panel of marine experts said there was a "high risk of entering a phase of extinction of marine species unprecedented in human history". They said the challenges facing the oceans created "the conditions associated with every previous major extinction of species in Earth's history".
