Are pollution and trashing the planet signs that the end is near?
Yes, pollution and trashing the planet are signs that the end is near, though they will not destroy the planet. The world's end will come when God says it is time, not by human environmental collapse or nuclear holocaust. Such signs merely show how close humanity is to that appointed time.
Les explains that he is against pollution and trashing the planet, and his heart weeps when he sees trash along his beautiful valley road. He hates it, but he will not say that if we do not clean it up, we are going to destroy the planet. Instead, he says these are all signs that we are getting so close to the end. Men of this world are not going to bring the end of the world, and they will not bring a nuclear holocaust until God says it is time. God is in control, and He, not man, will deal with the planet's final destruction. Les also points to Israel coming close to losing its identity as another indication that we are closer than most realize.
