Breaking Boundaries: The Science of Our Planet understands that it’s not the planet, but the human race that must be saved, and the only way to do that is to study how the planet works (know your enemy, perhaps?).

As Swedish professor Johan Rockström says, “biodiversity is not something we need to protect due to some kind of moral responsibility of one species, humans, towards another species such as flora and fauna”, but because “it is the toolbox for the functioning of our societies.”

Rockström is a proponent of Planetary Boundaries, a conceptual framework that assesses the state of nine processes fundamental to the stability of the Earth system, and suggests a series of thresholds for these processes that, if overcome, can endanger the habitability of the planet.

These thresholds are one-way doors; once crossed, there is no going back. Greenland, for example, is apparently fubar, as are half the corals in Australia’s Great Barrier Reef.

Rockström is Swedish, and that’s the only thing he has in common with Greta Thunberg. While she is a shrill, sanctimonious, self-righteous, malnourished bitch on wheels, Rockström is calm, cool and collected (by the way, the documentary is hosted by David Attenborough, a paragon of avuncular bonhomie); furthermore, Rockström actually sounds like he knows what he’s talking about, and is much easier to take seriously.

Additionally, Rockström demonstrates a deep understanding of human nature; accordingly, he cuts to the chase and appeals to people’s selfishness as a catalyst for change. And why not? He’s aware that the average a--hole never listens to the science anyway.
