There was this campaign carried out in 1994 on the dangers of dihydrogen monoxide (DHMO). The author alerted of its rusting, corrosive, and acidic properties. He urged people to support the bill for outlawing it.
A lot of people see the 2021 Adam McKay film Don't Look Up as something that fails to communicate the message of climate change well enough. McKay stated that the movie was written specifically to point people at the absurdity of the "climate crisis". And yet the film's allegorical comet / asteroid doomsday plot seems to fail at giving it justice. For once an asteroid that is about to destroy the planet is nobody's fault. While the climate change is somebody's fault. But if you look at the movie relatively to other disaster flicks of the same type ( like Armageddon and Melancholia ) you see something rather interesting.
