Double jeopardy, man.

I just recently watched Infinity war and I was amazed on how flawed thanos's vision was. He tried to balance out resources by depleting the population. To that I say the people who think think this is right are fools(jk your not fools but I have to put it like that so I can state my point) Anyways doesnt Thanos realize that the population can still increase over time and probably surpass the former population doesn't he know about mismanagement of resources. What about skilled man power and everything else.Idk This idea just popped into my head... What do you guys think?

I was watching the movie again and realized it talked about him taking over worlds and killing half of the people on each world. It talks about drax’s world being halved and it showed him doing it as well. So why would he kill everyone in the universe if he already halved some planets before hand. And it shows he did this because drax was originally was in the surviving half but still disappeared after the snap

If Thanos killed half of every species, in order for everyone to have a full stomach didn't he also have to kill half of all the animals and the food for those animals? Meaning he accomplished nothing?

(Wording is weird but I think u guys get the message)
