Just because it is too late for modern societies to be maintained, does not mean it is too late for influencing the future. Just because it might be too late to significantly influence that future, does not mean it is too late to learn how to participate less in destructive or delusional behaviours.
Look behind you. See your sons and your daughters. They are your future. Look farther and see your sons' and your daughters' children and their children's children even unto the Seventh Generation. That's the way we were taught. Think about it: you yourself are a Seventh Generation.
