“Thinking like a planet” is so alien to the perspectives of modern life—so far from thinking like a neoliberal subject in a ruthless competitive system—that the phrase sounds at first lifted from kindergarten. But reasoning from first principles is reasonable when it comes to climate; in fact, it is necessary, as we only have a first shot to engineer a solution. This goes beyond thinking like a planet, because the planet will survive, however terribly we poison it; it is thinking like a people, one people, whose fate is shared by all.
