The snap was always the dumbest part of the entire avenger series. Let’s say for example, you have a bunch of deer that are eating the forest bare, so you let hunters kill half of them… Then what happens next? You have the exact same problem in a few years. The snap solves nothing.

Also if you can snap your fingers and do this, why can’t you snap your fingers and make twice the food supply?

The snap is just stupid, even in a world made-up physics-defying superheroes.
