When I was growing up in the 80s and 90s, my parents generation were mostly convinced the world was about to end. Whether it was nuclear holocaust or some type of biblical Armageddon scenario, everyone seemed to agree that "the end is near"(TM)
The end is still near. It's called global warming. Unfortunately, it will be a slower and far more painful death than nuclear war or the Biblical Armageddon. And there's no way to avoid global warming since our survival (at current population levels) depends on burning fossil fuels.
