Like all Attenborough-fronted nature docs, “Ocean” is gorgeously shot and an immersive viewing experience. But while the vast majority of his output leaves you speechless at the on-screen beauty, “Ocean” also strikes you dumb at the horrifying devastation wrought on the open seas by the 40,000+ super-sized fishing trawlers operating around our planet constantly.

Sweeping the seabed with their giant nets, these ships commit slaughter on an unimaginable scale, leaving little alive in their rapacious search for a few specific species that humans actually eat. In their wake they leave something akin to the dystopian portrayals of a nuclear winter in post-apocalyptic dramas. These grim, heart-breaking shots are interspersed with glorious, vibrant scenes of what a healthy seabed should look like — towering forests of kelp, sea meadows, abundant diverse communities of extraordinary marine life… A reminder of what we are destroying every minute of every day.
