It seems like we've nearly eliminated famine, probably aided by the popularization of shipping containers in the 1960s.

While there is still substantial malnutrition in the world, it's going to be hard to parse through that data to figure out how much of it is people struggling to find food vs. people choosing to eat food that isn't nutritious.

But looking at the total number of calories the world produces each year, we certainly have enough to give all 8 billion people the 2,000 or so that they need (though distribution still needs some work). This wasn't the case until ~50 years ago.
