I just had the opportunity to watch this remarkable film on the big screen today. I recommend it! It is breathtakingly beautiful, as you would expect, but also very effective at communicating the violent monopolisation of the oceans that we, the human race, have been engaging in.
At the end of the film David Attenborough highlights the UN ocean conference happening in Nice imminently. Something I was totally unaware of: https://westmed-initiative.ec.europa.eu/events/2025-un-ocean-conference-9-13-june-2025-nice-france/#:~:text=Co%2Dorganised%20by%20the,and%20sustainably%20use%20the%20ocean.
I hope conference delegates have the chance to see this film before they go. And that movers and shakers in their countries also see it and therefore realise how important conservation of the oceans is for our planet now.
The film is very hopeful. Apparently significant areas of ocean have made a remarkable recovery once they have been left alone and given time and space.
It seems totally unnecessary for us to be trawling the oceans in the way we have been doing for some decades now. The footage of trawlers was horrendous. I think the only reason this practice has been legal is because it happens out of sight a long way away. Now it’s not out of sight, thanks to this film crew.
Underneath all of the devastating practices lies endless, insatiable greed. The one thing all this industry relies on.
But there are a few stories in the film that show greed doesn’t have to be the whole story. The global campaign to save the whales, which I remember happening in my childhood, was incredibly effective. Whole species of whales were saved from the brink of extinction and whale populations in general are now thriving again.
Also, there’s a little village in the film where the people decided to stop fishing nearby altogether when that patch became a protected zone. One of my favourite scenes in the film is of a group of their children jumping off the jetty there into a beautifully restored, clean ocean, full of colour, light and life.
And in Hawaii there’s a vast area of ocean nearby that the people decided some time ago to protect and make a « no take » zone (called Papahānoumokuāke). Over the past two decades, that bit of ocean has recovered remarkably well, and of course because of this, tuna stocks in neighbouring areas have increased by over 50% as well.
Although the film was explicitly not saying fishing and fishers are evil, it was saying we need to protect much more of the ocean than we currently do (currently less than 3% of our oceans is properly protected). I will be paying more detailed attention to the amount of fish in my diet, and to where the fish comes from in response to this.
This was a beautiful but uncomfortable watch. Ending with pictures of David standing on Old Harry Rocks, which is a beautiful stretch of coastline near where I grew up. As he says, protecting our oceans could protect the whole planet, our home.
