Breaking Boundaries: The Science of our Planet

This film is among the first mainstreams efforts to explain environmental limits (such as the Paris Agreement's limits on greenhouse gasses) to the broader public. Hosted by David Attenborough and Johan Rockström, and based on the Planetary Boundaries Framework, the film provides a good summary of nine key earth system processes and explains how abrupt and irreversible changes are likely to occur when key “limits” or “boundaries” are trespassed. The film will help to acquaint you with the concept of thresholds, and will explain how close we are to exceeding them, or - in the case of climate, biodiversity, and other process - how far past we have already gone.
