I remember, nearly a decade ago, watching a video on YouTube. In the video, the hosts of the show, consistent with their political leanings, filmed their infiltration of an environmentalist rally. There, they spoke with attendees and asked for signatures on their petition to ban a purportedly dangerous chemical. This chemical was largely unregulated, had been detected in our water supply along with countless food items, and could cause death within minutes if inhaled in sufficient quantities. The chemical in question was described with the scary-sounding name, “dihydrogen monoxide.” You might know it better by its chemical formula: H2O. Largely unregulated, in our food and water, it can cause death if inhaled in sufficient quantities, it was water.
