It's amazing how little trash a nation of slaves generates. Also, very few emissions. It is always Earth Day in North Korea, as the nation does a remarkable job at conserving electricity[1], unlike decadent Western societies.

In a life where you have nothing, you do not throw trash away. A lot of stuff gets re-used.

"Fuel constraints and the near absence of private automobiles have relegated road transportation to a secondary role. The road network was estimated to be around 31,200km in 1999 up from between 23,000 and 30,000km in 1990, of which only 1,717 kilometers—7.5 percent—are paved; the rest are of dirt, crushed stone, or gravel, and are poorly maintained."

Given how orchestrated tourist trips in North Korea are, I would imagine the only roads you are allowed to see are good roads.

I also wonder about traffic; is it like The Truman Show, where you see the same cars over and over again.
