Extinction Rebellion
Columbia's chapter of Extinction Rebellion was established in 2018 under the simple premise that EcoReps was "just too nice". While their characteristic method of "civil disobedience" might sound cool, their November 2019 attempt at a hunger strike in Butler Library only lasted five days, a full five days shorter than the participants in the 2007 hunger strike. What amateurs.
Cynicism aside, Extinction Rebellion was instrumental to the establishment of the Climate School and worked with Michael Gerrard to propose a divestment strategy for the university, which is still under consideration by ASCRI.
