Strange Disaster SIM

Now, I am become Death, the destroyer of worlds.

Choose a strange influence to impose on this world and see how this fragile ecosphere collapses - or overcomes difficulties.

1. Crops Degradation - Just in one night, crops on Earth have regressed back to their primitive state thousands of years ago - wheat and rice become shriveled, corn become thin, fruits have become more seedy and astringent. Humanity now needs to re-domesticate crops - despite humans' historical experience, the short-term impact cannot be ignored.
2. On Avery Island - Humanity entered a golden age, where countries put aside their hostility and sought development with the goal of exploring extraterrestrial habitats. However, the good time did not last long as humanity encountered a critical technological bottleneck. Space travel is proved to be a scan, a large number of scientific researchers lost their jobs, and the world economy also collapse.
3. Shared Suffering - The sudden onset of brain mutations has led humans to share each other's pain. A person's pain now radiates to the minds of others within two kilometers around them, and can continue to spread from the people who are irradiated.
4. Eternity of Antinatalism - Humans no longer be able to reproduce, however, they will also no longer age - the current age of all people has been frozen. Nevertheless, humans can still be killed.
5. Mist of Falsehood - A common hysteria is quietly spreading among humans. Nowadays, when people's brains learn information through language or words, they automatically distort or forget a small part of it - people can never know the "truth".
6. Absolute Anthropic Principle - If the existence of the universe is for the purpose of obtaining human witness, then the world has even become more obsequious now. The universal understanding of humanity now influences the fundamental rules of the universe, and if humanity generally agrees that 1+1 equals 3, then this is the fact.
7. Returning to Carboniferous - Plants on Earth have restructured their chloroplasts, almost doubling the efficiency of photosynthesis. At the same time as crop yields increase and plants become huge, the oxygen content in the atmosphere also sharply rises.
8. Among Us - People have learned that some non-human beings are disguising themselves as humans, lurking in society, and have been doing so since ancient times. However, humans are still unable to identify these disguisers and are unsure whether their existence will have a positive or negative impact on human society - they are simply convinced that these things exist.
9. The Foundation of All Epistemologies - After a sudden psionic awakening, people find their brains are no longer bound to their bodies. Now, human brain can detach from the body, move in the air under the drive of psychic energy, and feed on the brains of other large mammals, parasitize and control them. "Humans" have become terrifying parasitic creatures.
10. These challenges are nothing. Think another one.
