Throughout the entire history, different societies competed against each other in wars, trying to prevail one over the other.
Different people tried gaining power in society, competing against other people in society.
Such competition always resulted in a victor.
However, every time victory was achieved, the competition didnt end.
New enemies rose, and competition continued.
It was all fine and well, until competition started giving birth to great and powerful technology.
It was a logical path of competition, of competitors, to use technology to win and to produce more technology to win more.
However, technology, by being produced, gave birth to new problems:
1. It is no longer possible to compete without technology
2. Technology made competition more destructive by enabling destruction on a mass scale
3. Technology enabled mass wars, and mass populations. Mass populations led to pollution and overpopulation, and depleting of resources.
By making possible of mass farming, through the invention of tractors, technology made it so that country no longer had to place majority of population to work in agriculture.
This made it possible to have more population available for militaries. Therefore, all countries who wanted to compete had to apply tractors.
In order to compete, country must have great population or be part of an alliance that has great population.
Tractors made it possible to increase population greatly.
Societies that have large populations will prevail over those who have small populations.
This brings us to problem of increasing and not increasing population, both options being bad for society.
Today's societies are faced with struggle of two opposite options:
1. Take meassures to decrease your population, and be conquered by societies who choose to keep increasing theirs.
2. Keep increasing population, causing mass pollution, overpopulation, drain on resources.
The competition between humans before always resulted in winners and losers. That was before technology.
However, today's technology made it possible for there to be a conflict without winners, by the invention of nuclear weapons. Nuclear weapons made it for the first time to be possible for there to be a conflict in which everyone loses and gets destroyed.
Therefore, competition between humans is bringing humans closer and closer to destruction, irrelevant of if destruction is from nuclear weapons or from overpopulation or from pollution or from lack of resources.
Humanity must put an end to competition. If not, it is likely that this competition will put an end to humanity.
So the historical lesson tells us that humanity must unite into one society. If it stays divided on groups, competition between groups will destroy all.
