In "The Road":
- Sources of food (especially given it has been about a decade? since the apocalyptic event) were very scarce since all vegetation seemed dead and most, if not all non-perishables have been scavenged over the years
- Sources of water, however is abundant, through precipitation
- Sources of fuel appeared to be non-existent, no drivable vehicles were seen
- Cannibalism is rampant, the stronger and better equipped seem to prey upon the weak
- No signs of "civilization" such as towns or villages
In "The Book of Eli":
- Sources of food AND water are scarce, though the antagonist used his "pre-apocalypse" knowledge of underground water sources to gain power over the people of his town
- There are some signs of civilization, such as the "Ghost Town" that was revived by the antagonist and the setup in Alcatraz albeit they were few and far between
- There was no form of currency like caps, it was a straight barter system, determining mostly what was valuable at that moment
- There are some working vehicles and enough fuel to run them, again controlled by the antagonist
- Cannibalism exists, but is shunned by those who are more "civilized" and practicing cannibalism seems to lead to some type of disorder where you cannot keep your hands steady
