This is looking at global data. Most countries are a lot less wasteful than the US. It also completely disregards waste food, though it says it only makes up 5% of global caloric production.

According to the article, the US produces 14% of all agricultural calories on Earth. 28% of this is spent on non-food purposes, while 17% is spent on food but not animal feed, compared to 15% and 45% globally. This means that while the US produces twice as much calories per acre of farmland than the global average, it can actually feed fewer people per acre than average.

On this chart Norway would also be listed with 29 guns per person. These are owned by only 10% of the population however

Wait, so you’re saying the average Norwegian gun owner owns 290 guns? That sounds very implausible.
