Bit of a misnomer there, the world doesn't need saving. It'll be just fine if humans go extinct, and even if we take out most other forms of life along the way. We need only to save ourselves, from ourselves. I suppose I can agree with the general sentiment, though: we're not acting with enough urgency to prevent any of the existential crises facing us today, only enough to slightly delay the consequences.
Now where's the revolutionary thinking in that? Fate can be denied, the roles set upon us by others can be shirked, and strings can be cut. Granted, Americans on average are far more complacent than we have any right or reason to be, but the US is not the world, and so I choose to remain somewhat optimistic.
