We have not found aliens because climate change makes them extinct?

Where did aliens go? We humans have sent them one, looking for their sign on Mars and beyond that in our solar system. We even built many observatories to listen to the sounds from them. But until now, no aliens appeared.

This is a very painful hypothesis: what if I die? Cause?.

Maybe, aliens have completely disappeared because of climate change.

If this hypothesis is correct, it will be a bad sign for us. Not only because of the search, but we have spent so much effort to pour the river into the sea, but because our own future will probably not be so different!

According to the article on Futurism, this hypothesis was published in a study published on May 1 in Astrobilogy magazine. A group of researchers from the University of Rochester has used mathematical models based on a real civilization that has disappeared to find out if other civilizations, whether human or extraterrestrial how will it respond when faced with a catastrophic climate change that leads to the reshaping of a living planet

When it comes to civilizations that lead themselves to destruction, there are no more obvious examples.

"Easter Island is a very concrete example because it is often taken as a lesson in global sustainability" - Adam Frank, the study's lead author, said - "Many studies show that Easter Islanders Birth used to exhaust their resources, leading to hunger and extinction of the whole civilization on the island. "

More importantly, Easter Island used to be a closed system - that is, isolated from the larger communities outside, so that island residents have nowhere to go when the resources they live in are gone. half.

By establishing models of Easter Island residents in parallel with their rapidly depleted natural resources, the team was able to come up with many possible outcomes for any civilization based possess limited natural resources (like our Earth!).

The charts above were created by Frank's team, showing four outcomes that occurred with the fate of a civilization. In case A, named "Die" , the population grows so fast that the habitat is not enough to respond.

"Imagine the scenario that 7 out of 10 people you know can die quickly" - Frank said - "It is not clear whether a complex technology civilization could exist if such a change occurred or not."

In the case of C and D, we have two different types of "collapse" , and an increasing population faces a rise in the planet's temperature. In one case, civilization continued to grow without offering any corrective measures and quickly using up resources. In the other case, civilization shifted to sustainable development, but the changes made were too small, too late, and their fate was no better.

Fortunately, there is a case where civilization does not completely collapse. That is the case B: sustainable. In this model, a civilization reacts to the threat of climate change by adopting sustainable solutions early enough to save itself. The population now decreases without leading to the collapse of the habitat.

But sadly, our human civilization seems . there is no sign of that lucky ending.

There are many theories that are designed to explain why we have yet to find other life forms, including a theory of mass extinctions that all civilizations must overcome. How visualizing alien civilizations will face similar global threats will probably help us better prepare ourselves.

After all, the difference between survival and doom in every case revolves around how early: that civilization reacts to the shortage of resources.

"Through space and time, you will find winners - civilizations who are aware of what is going on and find a way to overcome it - and those who fail, those who cannot act together and then their civilization fades into smoke " - Frank said.

"The question is, what situation do you want our civilization to fall into?"
