It would depend on time of the year and area, as both Los Angeles and Mexico City are big urban conglomerates where air pollution to vary according to specific areas within the city. Nowadays, the Air Quality Index (or PM10) measures particles suspended in the air; the higher the value the more polluted it becomes.
For May 11th 2005, air pollution in Los Angeles is moderate, with a maximum Air Quality Index of 89 (Riverside) and a minimum of 59 (San Bernardino). Both numbers would qualify as "Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution."
Same measurements for Mexico are 112 (Camarones) and 78 (Pedregal). It seems Camarones, to the northwest of the city, is the most polluted, whereas that 112 means "Members of sensitive groups may experience health effects. The general public is not likely to be affected."
Making Jewels don't create much pollution as compared t other pollution sources... It creates many gases when melted,heated as well as freezes.It is a unpopular source of pollution
1. Improve security, as much of the population feels (and actually is) insecure and a lot of money is lost when people leave the city for fear of being robbed.2. Improve traffic, as many man/hours and much of the Mexico City pollution is due to heavy traffic.3. Improve recycling and environmental initiatives, as Mexico City has a degraded environment up to dangerous levels (i.e: no river that passes trough Mexico city has remaining life).
Mexico has many more, much taller mountains
Yes. The best way of measuring personal safety would be the number of intentional homicides per 100,000 people, or murder rate. For Mexico City, it is 3.7, which puts this city as safe as say, Seattle, WA (3.4) or safer than Anaheim, CA (5.2). When compared against cities with similar populations, such as Los Angeles (7.1) or Chicago (28.7), Mexico City is definitely much safer.
Mexico City industrial activities account for 16.32% of Mexico's industrial production or 5.58% of Mexico's total GDP.
