It’s only the humans who died not animals or plants. And population
ballooning up isn’t granted, with comfortable living and a higher demand
on education or work, they could see less births each year similar to
Japan and the USA’s rates. Overpopulation is indeed a serious problem
and a strain on resources. But yea he could’ve just done with more
resources. To be fair though the comic version was fucking stupid and
painted thanos as a two dimensional corny ass crazy dude. I much prefer
Fuckin’ incorrect. The Marvel Studios CEO himself said that plants and animals were killed too. Half of all living things in the entire universe.
The plot was r e t a r d e d and you’re wasting your time trying to defend it. Especially because you’re ignorant of what actually happened in it.
