The core problem is the Butterfly effect in our world. Starting with the Telegraph system going world wide, that not only founded the CIA by having their founders meet in a Navy Telegraph Station, actions can have incredible leverage.
Sherlock Homes is using such chains as an investigator, but the novels are turned into fiction. Humberto Eco's Foucault's Pendulum explores the same effect and cause systems all human action is based on diving into secret societies which founded our secret services as their technical predecessors.
We all understand from watching and consuming the media that Cocaine causes a very lot of violence and decay for not only individuals, but also entire regions populated by millions of none using humans. It still is loved.
For some organizations actions have no legal consequences no matter being publicly known with even solid proof.
We almost ended all in a Nuclear War not only once during the Cuba Crisis.
The last time we as mankind faced significant technical changes we had major development in agriculture that enabled us to harvest much more while having much less work.
Towns turned Cities.
But mankind also faced a epidemic that took down incredible amounts of humans reaching into large two digest estimates of up to 80% in Europe.
We are still in the Industrial Revolution that came along with the Spanish Flue, HIV and now Corona, but also Climate Change, Secret Service crime, Hard Drugs, Mass Surveillance and the biggest economic miss-match world wide unmet in mankind's history even so we can turn the Desert Green, have cutlery for everyone, 50cent meals in need of only water and regions in which buying meals is cheaper than cooking being able to visit most foreign areas in just hours.
Cities turned Metropoles and now Regions into Sprawls.
There is no way that we do not face another death wave by drugs, virus and violence considering mankind's history and our currently failing systems to provide fairly to everyone even justice...
...World Wide, not only in a small fucked up, way past its glory Valley in Europe surrounded by drugged, corrupt Nazi cops excluding the legal system being scared of the gang action coming up understanding yet struggling to accept what they always were to everyone in the game of how mankind is ruled.
Egoism or Selflessness
