Watch Who Farted?

While watching his twelve-year-old daughter's school science project, Albert Nerenberg has a life-altering experience. The children describe how cow flatulence plays an outsized role in greenhouse gas generation. As the methane contained in bovine farts combines with CO2 pouring out of the world's factories, automobiles and airplanes, it seems we are farting ourselves to oblivion. A frightened student, voice quavering, asks if farts will kill us all. Albert, shaken by his daughter's revelations, sets out to discover the truth -- a decision reinforced after Albert personally witnesses climate disaster in his own neighbourhood.

Who Farted? is a 2021 documentary with a runtime of 1 hour and 18 minutes. It has received mostly positive reviews from critics and viewers, who have given it an IMDb score of 6.5.
