Defending our Oceans

Seen from space the Earth is covered in a blue mantle. It is a planet on which the continents are dwarfed by the oceans surrounding them and the immensity of the marine realm.

Marine reserves

A growing body of scientific evidence that demonstrates what we at Greenpeace have been saying for a long time: that the establishment of large-scale networks of marine reserves, urgently needed to protect marine species and their habitats, could be key to reversing global fisheries decline.

Pirate fishing

Armed and masked, scouring the oceans, stealing food from hungry families – modern day pirates are a far cry from the glamour of Hollywood movies. But they are a multi billion-dollar reality for many communities that can least afford to be robbed.

Overfishing

Many marine ecologists think that the biggest single threat to marine ecosystems today is overfishing. Our appetite for fish is exceeding the oceans' ecological limits with devastating impacts on marine ecosystems. Scientists are warning that overfishing results in profound changes in our oceans, perhaps changing them forever. Not to mention our dinner plates, which in future may only feature fish and chips as a rare and expensive delicacy.
