Seven Worlds, One Planet
6.15pm, BBC One
Following a brief foray to Netflix, the nation’s favourite conservationist-cum-grandpa David Attenborough is back on the Beeb with a seven-part series, each episode of which explores one of our seven continents. There is a palpable sense of ecological concern in this opener as Attenborough’s team travel to Antarctica and reveal how the natural world survives in such a hostile landscape. Expect ice-grinding seals, tear-jerking pups and waddling king penguins. A glorious, 4K odyssey for your Sunday. Ammar Kalia

Why We Hate

This third episode of the Steven Spielberg-produced doc enlists writer Jelani Cobb to examine how hate tools – propaganda, dehumanisation, the internet – fuel our latent hostilities.
