Elements of hazard
The elements of hazard are Acid, Lava, and Poison (ordered here by date of discovery). Every trouble, danger, or harm currently known can be attributed to one or a combination of the elements. All three elements at full concentration produces Death.
The elements are thought of to be the anti-form of Food, due to their equal and opposite properties.
Acid contributes to a danger the element of corrosiveness. This is what gives bacteria its ability to decompose shit.
Lava contributes to a danger the element of heat. Fire is lava in small doses, while gamma rays are lava in big doses.
Poison contributes to a danger the element of pain. Without it, the hazards of the world would pass through you like butter.
World-renowned Wiki Camp scientist Mark Rober attempted to do a comparison between these three, but forgot about acid!
All three elements appear in the hit Disney game, Where's My Water?
