You don't have to be a cynic to ask yourself whether mankind is even worth saving and surviving the coming crises. If you tell others about positive visions of the future, you often only get a tired smile. Hasn't mankind proven enough in its history that it is an irrational, aggressive and violent being? How could it happen that mankind, despite all its cultural, scientific and technical achievements, is on the brink of self-destruction today? Wouldn't planet Earth be much better off without us humans?
I don't think we should limit our view of human history to what is written in our history books. That is as good as nothing compared to our prehistory. In order to understand the value of our evolution, we need a more comprehensive view, a "Big History". Take a look at the article "How 'Big History' can safe the world" published six years ago by Democracy Without Borders!
"It may not be too much to hope that this broadened perspective could eventually help lay the foundation for the eventual political unification of our world. In a powerfully argued recent analysis, Jo Leinen and Andreas Bummel have concluded that such political unification, perhaps in the form of a federal world government, may be necessary if the pressing global problems of the 21st century are to be addressed."
From the "Big History" to the "Big Future"
When I read the novel "2061: Odyssey Three" by Arthur C. Clarke some time ago, I remembered that in many science fiction stories the political unification of mankind is taken for granted. In his novel "Childhood's End", Clarke had aliens force humans to elect a world government and realise world peace. As in most plots of this genre, esoteric fantasies also gained ground here. UFO believers propagate a "Galactic Federation of Light" to save the world. A wide field for storytellers.
But science fiction in particular contains interesting mind games for ideas about the future, provided that the laws of nature are observed. In his 1968 work "Voices from the Sky: Previews of the Coming Space Age", Arthur C. Clarke developed realistic visions for the future of mankind. It could be a great future. Homo sapiens today is indeed on the threshold of becoming an interplanetary being. Should everything be wiped out just because mankind seems too stupid and unworthy to reach such a level of development?
Mankind is worth it
"Only bad news is good news" is a well-known phrase in the media business. We receive predominantly negative news every day, making the world seem like a giant madhouse. Let's not be fooled by this! The world is better than it seems. If people don't allow themselves to be seduced by political masterminds, warlords, religious fanatics and mass murderers, they are already united in their basic needs. They possess characteristics that are equally present in all individuals. These characteristics have such a great unifying value that external characteristics of physique or skin colour resulting from descent are irrelevant. Social or cultural differences also pale in comparison to the similarities. Anyone travelling the world with open eyes can see this everywhere. These are the people that United Mankind needs.
Let's go in search of these people!
In order to initiate a movement, you first need a personal base. This base does not have to be large, but its participants should be aware of their task and become active for the cause - each according to their possibilities and abilities. The point is to find such people. They would be the first members and companions on the path to United Mankind.
There are many places all over the world where you can find these companions. You could do it like the international Registry of World Citizens. But that would be too much bureaucracy to start with. Also, the benefits of world citizen ID cards are disproportionate to the effort required for them.
Perhaps the simplest method could be to look for companions on social networks on the Internet. I have started a trial on Facebook. Anyone who is interested can join the "Members of United Mankind" group.
