I would be surprised if it were true of the Japanese, but not the Chinese. The interior populations have been expanding over the years with some forced relocations and attempts to further develop those areas in comparison to the coastal regions where everyone is packed in. With it the pork consumption has increased as well.
Noted. Good info - thanks.
Still, I was surprised that (before this virus) the Chinese had, literally, over 3x the number of hogs as the US. Most of the pigs dieing of this disease would have to be a huge shock to their food supply system.
