Cities and Pollution

The pollution in cities around the world is classified into two components:

1. Smog and 2. Particles. Particle pollution refers to the microscopic soot like particles produced by power plant emissions, diesel exhausts, wood burning and other sources. The other considerations are whether the pollution is short term or year round. In some cities, the levels of pollution have become dangerous.

In the United States , Los Angeles , California is rated the worst city in all areas of pollution, while Santa Fe, New Mexico is rated the best. Pollution has a great deal to do with population. Quantity always subtracts from quality. The greater the demand on sewer systems, transportation, manufactured goods and water and electric services, the greater the pollution problems.

Pollution is a worldwide problem. In Europe, London and Paris are having problems. Athens , Greece is the worst. However, nothing touches the pollution levels of Mexico City , Mexico . It is rated as the dirtiest city on the planet in all categories. Pollution is reaching the point where if we don't all deal with it, it will deal with us. In the U.S. , 55% of all Americans live in an area with unhealthy levels of ozone or particle pollution. Zurich , Sweden is rated the cleanest city in the world.

It would seem to me that we should find out what they are doing, or not doing, in Zurich , and apply it to the areas we live in. With world population continually on the rise, the quality of the air we breathe should be a very high priority, shouldn't it?
