The problem we face is population control. No one knows how to enforce it or even how to suggest implementing it. Our ancestors who had the Earth to their selves had plenty of space if you could remove the local wildlife. But having children was an imperative to them. The fight for resources is what actually divided the human race and the Nations we know today. Once we were Earthlings and now we are secured in place by a nationality, this is how we lost our way. We started to compete and fight one another which has started the world of war we now live in. The reason World Peace does not exist is because there are no peaceful people to make it a reality. If it were so you would be an Earthling surrounded by mothers fathers daughters and sons of the human race traveling the endless Stars and surviving time and space. But because we are not peaceful people our leaders use War to kill our children to reduce our populations and begin the game of indoctrination to whichever Nation you belong. I'm not sure if it's any better than slavery but you are surely not free. Our capabilities have been stifled and prevent our power from reaching each and every soul. But that leads back to the first problem population control. If we truly become peaceful and free, collaborating together to engineer the future where every human being on Earth is provided everything they need or want  we will guaranteed overpopulate the planet. So we as a species must figure out how to control our population growth or cure the apparently desperate need to fuck.
