Polluted oceans

Almost half of the oceans have been badly damaged by humanity and no region has been left untouched, the first global map of Man’s impact on marine ecosystems has revealed.
The ambitious project to chart the changing ocean environment shows that Man has exacted a much heavier toll on the seas through fishing, pollution and climate change than had been thought.
In many regions the effects of these are combined with pollution, particularly run-off of fertilisers from agricultural land and invasive alien species that are often introduced in the ballast tanks of ships. Link here.
