In the Avengers Infinity War movie, after getting hands-on all the infinity stones & putting them into his Infinity Gauntlet.
Thanos wiped out half of the world’s population using its power in just a snap.
But what if this event would have taken place in real life, a scientist from UCLA ‘Justin Christensen’ has explained its aftermath to Fandom.
If this deadly snap had happened in reality, our population would have fallen back to 1970s. It is true then we would have a lot of resources & food for ourselves, but modern day facilities won’t be available especially medical supplies.
Humans would have to repopulate again to reach the population of 2019.
Justin also stated that if pilots, bus drivers, air traffic controllers and the like were all instantly snapped away, the number of non-snap related fatalities will increase.
But what if more than the human population were affected? Some fans were curious to know whether all living organisms were affected.
The writers of the Avengers Infinity War and Endgame, Christopher Markus and Stephen McFeely have answered this question.
They said that the snap would only impact “sentient life,” or only intelligent and conscious life forms like humans and animals.
But Marvel Studios chief Kevin Feige has different views on this, as he stated that the snap wiped out “All life!” which became the source of all confusion.
Christensen takes on both these statements by saying that “complex and fragile relationships between many different species” would be affected, and “many ecosystems [would] change completely, and there could be species that never recover.”
