Surviving after an ELE (Extinction Level Event) has occured

Many of us are aware that we're all about to face an ELE (Extinction Level Event) sooner or later.

However, it must also be noted that although the event may be classified as an 'ELE', there are chances that a very very small minority from among us may actually be able to survive the event(s).

What do the survivors do next? How does a man with no one by his side survive further? 

Watch this exciting series titled "Apocalypse Man" which aired on History Channel last year for techniques that may come in handy.
