If this were to ever come about, the world would be over populated within just a few short years (sooner than the current schedule) and we would all be in for it!
So you are saying that we wouldn't be smart enough to make it if there was peace? That killing is the number one choice for survival?
I think man and technology would go a long ways in development. Do you realize how big this plant actually is? The world is constantly being forced into moving forward. Ask anyone old. They will always say the good ole days are gone. Every generation says this. Like my grand parents were born before cars were built. My parents were born not having inside plumbing and using out houses. I was born with out color tv's and man hadn't walked on the moon yet , not even a ball point pen was invented. I still say LET THERE BE PEACE ON EARTH Just the mind power itself and the will to survive would guide us along if we were all in it together.
We can only hope and dream.
