Apocalyptic in the neighborhood

Seeing as how we must be in the beginning of the apocalypse with the leaves turning colors and falling off the trees, I'm stocking up on firewood. I heard people burn it if things get really bad and the temperature drops. So I started cutting down that large oak in my neighbors yard. He came out of his house screaming " What the Hell are you doing?"
I told my distraught neighbor "The trees are dying, see the leaves falling off onto the ground. So we might as well cut em down." 
Strange he didn't even thank me.
