The oceans’ natural resilience has been seriously compromised. Pollution, habitat loss and overfishing are dangerous threats on their own. But when these factors converge, they can destroy marine ecosystems.
The severity of human impact was reinforced last week when scientists concluded that seven commercially important species, including marlin, mackerel and three tuna species, were either vulnerable to extinction, endangered or critically endangered according to I.U.C.N. standards. The solutions that might help slow further degradation include immediate reduction in carbon dioxide emissions, a system of marine conservation areas and a way to protect ocean life that goes beyond national jurisdictions.
This is the work of nations, but such goals require pressure from ordinary citizens if there is to be any hope of bringing them about in the face of opposing political and economic interests. As the new study notes, changes in the oceans, caused by carbon emissions, are perhaps “the most significant to the earth system,” particularly because they will further accelerate climate change.
