Vincent is trying to get the point across that we are destroying our earth even though it is the very thing that provides us with life. That we don't even care that it is being destroyed as long as we don't have to deal with the consequenses now. With all the war and fighting over meaningless things, the obvious end to us all will be a global nuclear apocalypse. The earth will be nothing but ash and fire and that is when we will have our regrets.
