The wonders of Blue Planet II have brought pleasure to millions, but not uncomplicated pleasure. Because, in the back of our minds has lurked the knowledge that the wonders are, in very many cases, endangered.
“The oceans are under threat now more than ever before in human history,” David Attenborough warns us in this sobering final episode. He doesn’t simply narrate, he presents, witnessing conservation efforts around the world and hearing scientists deliver sombre news. The effects of plastics, overfishing and climate change come through with real power in a documentary that may leave you sad, angry and chastened.
What time is Blue Planet II: Episode 7 on TV?
The final episode of the series airs on Sunday night at 8pm on BBC1.
What is going to happen?
The final episode takes a stark look at the impact of human life on life in the ocean.
The BBC urges that, despite depicting albatross parents unwittingly feeding their chicks plastic and mother dolphins potentially exposing their new-born calves to pollutants through their contaminated milk, the episode contains “an inspiring message of hope”.
Writing in a recent issue of Radio Times, David Attenborough spoke of one initiative in the past which he believes shows that humans are capable of reducing their negative impact upon marine life: “in 1986, the whaling nations of the world got together and agreed by a majority vote to stop doing so – except for a very few special purposes. Today, some whales have started to increase once again and now exist in heartening numbers”.
“Never before have we been so aware of what we are doing to our planet – and never before have we had such power to do something about it,” he added.
