To understand why your character is driven toward a certain goal, get to know their positive and negative traits, as well as any significant emotional wounds that might be motivating them. Then you can explore the various kinds of conflict that could block them as they move toward their goal.
FORMS THIS MIGHT TAKE:
From a natural disaster, such as a supernova, climate shift, or superstorm From an unnatural threat (aliens, zombies, demons, etc.) From a power-hungry dictator, country, or other armed force From a plague From an extinction-causing event, such as worldwide female infertility or the death of all children From a mutation of natural predators or a shift in their population numbers that put humans at risk
HUMAN NEED DRIVING THE GOAL (INNER MOTIVATION):
There are five basic human needs that, when missing from a character's life, could motivate them to pursue this goal. The following needs are all possibilities, but only one of them should be the primary driver for any given character. For more information on the relationship between human needs and outer motivations, please see this Character Motivation tutorial.
Physiological Needs: Survival is our most basic and primal instinct. When one's life, and the lives of loved ones, are on the line, a character will be driven to great lengths to save them.
