The document is a satirical webpage advocating for the banning of dihydrogen monoxide (DHMO), which is water. It describes DHMO as a colorless, odorless, and tasteless chemical that is found worldwide and kills thousands each year through accidental inhalation or prolonged exposure. While DHMO has many legitimate industrial and medical uses, the webpage argues that companies are allowed to contaminate the environment with it and the government refuses to ban its production and use. It calls on readers to help stop the "horror" of DHMO contamination by contacting the provided Coalition to Ban DHMO.
