User: Was Thanos right ?
Assistant: In the 2018 sci-fi movie Avengers : Infinity war , the main protagonist “Thanos”, was obsessed with the idea of resource management . In a flash back to his story, he revealed that his planet suffered from overpopulation and hence lacked the necessary resources to maintain that society. The society and planet had subsequently ceased to exist. Thanos then believed that only by population control can you better manage the resources.  He set about to exterminate ½ the population of the galaxy. 

Thanos did succeed and as the 2019 blockbuster Avengers : Endgame and subsequent TV shows suggested , there were some positive environmental benefits to a reduced population. The issue is , and without stating the obvious that genocide is wrong , is that even with a reduced population, that rate that which humans would repopulate the world in the next one hundred years,  as a consequence of such staggering loss, would be exponentially faster than the last hundred years. Thereby defeating Thanos, plan for resource management. Instead Thanos should have explored technology for maximizing the longevity of those resources or looked at more sustainable solutions.
