But Mexico is a little close to California and the Pelicans might be in trouble depending on which way the wind is blowing. We might have to move things a little farther south, say Costa Rica or Guatemala. The federal EPA has been testing the air for many years now. There are some places in the country that have poor air quality. This isn't due to cars that have not been maintained, but a combination of industry and mother nature trapping the air.
LA is like a bowl with a lid on it.
Air is trapped and the pollutants can't readily escape. No amount of auto pollution testing is going to change that. But the problem with the EPA is that when air quality is improved, they panic because if the air is clean, they don't have jobs. But since they control the standards, their problem is not a problem. All of a sudden, pollution is a big problem again and they all get to keep their jobs.
