>>Germany’s population density is 593 per sq mile vs China’s 365. However, I’d say it’s a good bet that no one in Berlin burns firewood for heat or culinary purposes, whereas in China, those who don’t are probably the exception<<
LOL. Ironically, Berliners doesn’t burn firewood because they inherited a Soviet style centralized steam heahing system.
In the West burning wood for heat is pretty common to cut on electricity and natgas. Me personally witnessed tons of firewood in backyards of quite opulent Munich neighborhoods and I’ve seen their stoves too.
Their stoves are presumably a little less crude and less smog-prone than those of a poor country with 1/7 the GDP per capita.
