This will decide the outcome as to where humanity will end up.
Civilizations, even in our recorded history, have failed because of this fear and greed. Will we continue to make the same mistakes, perpetually destroy everything we've gained as a civilization because we cannot give up our small fearful ways, or are we going to act in strength and victory and move forward in time ever-expanding our potential and our fulfillment as a species, as divine humans?
The decision is a personal one. If every individual decides to act with integrity, keeping in mind that we are all citizens of this one planet, we will make it.
If we hold on to "fistfuls of dust" believing it to be our strength, our personal material gain and power the superior stance, we will self-destruct--as other civilizations in recorded history and unrecorded history have done.
From the spiritual perspective you could say it's not a big deal. The soul survives. But would you really want to be the one that, as a human personality, engaged in acts to destroy the world? As a soul, you'd have to repeat this lesson until you learn it. Or would you be the one who has triumphed, rose above personal fears, personal vendettas, personal greed, and been the one that has been the leader, the one who has firmly held to eternal values, who has led this civilization into unprecedented success?
