The world has arguably never been more in need of a hero. Someone to confront the vast existential threats posed by climate change; to unite global populations in the planet’s defence; and to inspire us, despite the magnitude of the crisis, to demand environmental justice ourselves.
In many ways, two such individuals already exist – 17-year-old Greta Thunberg and 94-year-old David Attenborough. At least, that is the implication of two new documentaries, Nathan Grossman’s I Am Greta, and Alastair Fothergill and Jonathan Hughes’s David Attenborough: A Life on Our Planet, both out this month. Members of very different generations, Thunberg and Attenborough share a single, passionate message: that humanity’s fate now hangs on our total realignment to the natural world.
