Since we as a species first harnessed fire as a tool, we have been engaged in a battle to control it. As one of the violent effects of combustion, we have tried, to no avail, to control it. 620,500,000 (approx.) days since we first used fire the goal of safely controlling it still eludes us.
Typically this works by cooling the fire and reducing its access to an oxidizing agent, but doesn't take into account the potential for lack of resources needed to fight the fire, or the expense of the chemicals.
Our problem is fire and the costs incurred in both fighting it and not fighting it.
