This is a digital Mercator map of the world, which is difficult to see behind the smog, or more accurately, the carbon monoxide. To put the map into perspective, the highest concentration of smog is on the left side of the map, which is cjina (SNL for China). Their smog spreads world wide. We we also generate smog, but nothing in comparison.
Obama was making progress with cjina, but then our latest president, not particularly thinking about the environment, dropped that focus to go after trade. Moving manufacturing back to the US would be nice, but perhaps even more important is to pressure cjina to clean up their's.
