There are many doomsday scenarios on Earth.
Alien invasion and the end of humanity,
an emerging virus will destroy all humans,
the world will run out of energy resources and primitive life will bring the end of humanity,
divine apocalypse that will take place when beliefs are exhausted,
the world and its contents will be destroyed by global warming and a similar natural disaster,
meteor hit the earth,
because of people's endless ambitions; that life on earth will end by itself,
many options like … and I'm sure many more examples could be added.
The most realistic of them are; it looks like a virus, global warming or some similar natural disaster. Divine apocalypse may not be a threat to the world for a while!
Or the options may change for you, maybe you have ideas to add or change the priority order.
If I were to write an apocalyptic scenario for the world, I would invoke the idea that an internal threat would destroy the world, rather than the fantasy that an outside threat would destroy it.
As traditional people say; fear the visible, not the invisible!
The resources in the world, on the ground and underground are constantly being exploited by someone… And after the exploitation, nothing is left as before. No one knows how long the world will endure this.
The possibility of nuclear wars overwhelms the fact that nuclear tests have taken place. Nuclear wars may not have started yet, but nuclear tests are constantly being conducted and new nuclear weapons are being added every day. Those who say they are against nuclear weapons and are trying to prevent them; The fact that they have nuclear weapons creates a different dark humor. We didn't forget Hiroshima and Nagasaki!
The number of nuclear power plants is increasing. We know about the nuclear accidents and the destruction they caused in the past. Moreover, there is no need to go far into the past for this, we have it in our recent history. The world is extremely energy hungry and everything is done for energy! Although it is presented as such, the result and the process continue to work against the world, regardless of whether it is real or not.
Every good thing has an end. Just as life began on earth, it will one day end for a reason. We don't know in advance what the cause will be, but we can speculate. Predictions that cannot be seen as true today may be the truth tomorrow. We do not know which generation will see the doomsday of the world, but I think that we will contribute more or less.
After all, everyone already has their own apocalypse. Everyone who is born dies one day. Those who think "Let there be a flood after me" do not need to think about the doomsday of the world or future generations!
….you are right….you are the knower…selfishness is perhaps the greatest treasure…if you can!
