[Avengers: Endgame] So everyone that was snapped away has just been brought back, is there enough food?

It's been 5 years since they were snapped away and food production has adjusted to the new population size. How on earth are we going to manage to feed double the population overnight?

Double isn't that bad for the west.  
The average western nation wastes HUGE amounts of food. And people can spin up a bunch of production fairly fast.

Power usage is far more concerning. And hundreds of support industries.

Sure you've got the people with skills like you always had, but there's new people in those roles now. Production lines and transport has changed. The entire world is thrown into chaos. millions of people in someone else's home. People have moved onto new relationships.

Food is probably the least disastrous of the horror it caused.  
And Far From Home significantly glossed over it all.
