The following passage states a key idea from the article:

In his book Young Men and Fire, Norman Maclean writes that dying in a  forest fire is actually like experiencing three deaths: first the failure of your legs as you run, then the scorching of your lungs, finally the burning of your body. That, roughly, is what happens to wood when it burns. Water is driven out by the heat; then gases are superheated inside the wood and ignited; finally, the  cellulose is consumed. In the end, nothing is left but carbon.

The article “Blowup: What Went Wrong at Storm King Mountain”  is a detailed description of forests fires, how they begin and spread up to huge lands.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
