I come forth to deliver a warning. The food you eat, the beverages you drink, the liquid running from all your taps – they contain the odourless, colourless chemical dihydogren monoxide. This chemical is known to be the basis of many adverse health effects, including gene mutation and cell lysis. It is home to countless pathogens and it allows the transmission of numerous diseases across the globe, yet we still expose ourselves to it every day. It has been and still continues to be a major cause of environmental erosion and the destruction of millions of residences worldwide.
