Blue Planet 2 producers say final episode lays bare shocking damage humanity is wreaking in the seas, from climate change to plastic pollution to noise

The Guardian ‘The world’s oceans are under the greatest threat in history, according to Sir David Attenborough. The seas are a vital part of the global ecosystem, leaving the future of all life on Earth dependent on humanity’s actions, he says.

Attenborough will issue the warning in the final episode of the Blue Planet 2 series, which details the damage being wreaked in seas around the globe by climate change, plastic pollution, overfishing and even noise.

Previous BBC nature series presented by Attenborough have sometimes been criticised for treading too lightly around humanity’s damage to the planet. But the final episode of the latest series is entirely dedicated to the issue.

“For years we thought the oceans were so vast and the inhabitants so infinitely numerous that nothing we could do could have an effect upon them. But now we know that was wrong,” says Attenborough. “It is now clear our actions are having a significant impact on the world’s oceans. They are under threat now as never before in human history. Many people believe the oceans have reached a crisis point.” Click here to read more – lots of links
