Unlike the original film where the aliens were concerned about nuclear war, the 2008 version shifts the focus to environmentalism. Klaatu is an emissary from a coalition of alien civilizations. He has been sent to Earth to determine if humanity is capable of changing its destructive behavior toward the planet. The aliens view Earth as a rare, habitable planet that must be saved from humanity's ecological damage. If humans cannot change, the alien race decides they must be "eliminated" so the planet can survive. Link Free Velamma Comics In Hindi Pdf
