Helen Benson: I need to know what's happening. Klaatu: This planet is dying. The human race is killing it. Helen Benson: So you've come here to help us. Klaatu: No, *I* didn't. Helen Benson: You said you came to save us. Klaatu: I said I came to save the Earth. Helen Benson: You came to save the Earth... from us. You came to save the Earth *from* us. Klaatu: We can't risk the survival of this planet for the sake of one species. Helen Benson: What are you saying? Klaatu: If the Earth dies, you die. If you die, the Earth survives. There are only a handful of planets in the cosmos that are capable of supporting complex life... Helen Benson: You can't do this. Klaatu: ...this one can't be allowed to perish. Helen Benson: We can change. We can still turn things around. Klaatu: We've watched, we've waited and hoped that you *would* change. Helen Benson: Please... Klaatu: It's reached the tipping point. We have to act. Helen Benson: Please... Klaatu: We'll undo the damage you've done and give the Earth a chance to begin again. Helen Benson: Don't do this. Please, we can change. We can change. Klaatu: The decision is made. The process has begun. Helen Benson: Oh God.
