The 75-minute production from 2021 follows the scientific journey of Johan Rockström and his team’s discovery of the nine planetary boundaries we must stay within, not just for the stability of our planet, but for the future of humanity.

This “planetary boundaries framework” serves as the structure of the film. With support from Attenborough’s voiceover and a global assembly of experts, Rockström details the impact of anthropogenic change on the nine processes, and where we stand in relation to the “irreversible tipping point” for each. In the case of at least four – climate change, biodiversity, land-system change and nitrogen and phosphorus imbalance – we are already operating in the high-risk zone.
