Hot on the heels of David Attenborough’s big screen rallying cry to save our planet comes this intimate documentary Swedish environmental activist, Greta Thunberg, who at only 15-year-old and having Asperger’s syndrome inspired a generation across the globe to go on school strike to demand immediate action on climate change.

We’re given Greta’s eye view of events as this otherwise very ordinary, shy and lonely schoolgirl is thrust into a media and political whirlwind.

Footage of her terrifying wind-powered voyage across the Atlantic Ocean shows it clearly not an empty gesture or a mere showboating of her credentials, and by the time she delivers an impassioned speech at the UN Climate Action Summit in New York I was fully onboard with her message.

Greta is understandably and deservedly cynical about the posturing of politicians, her modesty about her achievements in raising awareness is remarkable and her composure, resilience and humour in the face of appalling abuse from politicians will make you furious.

And if such a small figure can inspire such ire in powerful old men such as President Trump then she’s doing something right.
