Air pollution is usually concentrated in densely populated metropolitan areas, especially in developing countries where environmental regulations are relatively lax or nonexistent. However, even populated areas in developed countries attain unhealthy levels of pollution with Los Angeles and Rome being two good examples.

Famous quotes containing the word cities:

    How far men go for the material of their houses! The inhabitants of the most civilized cities, in all ages, send into far, primitive forests, beyond the bounds of their civilization, where the moose and bear and savage dwell, for their pine boards for ordinary use. And, on the other hand, the savage soon receives from cities iron arrow-points, hatchets, and guns, to point his savageness with.
    Henry David Thoreau (1817–1862)

    If I be false, or swerve a hair from truth,
    When time is old and hath forgot itself,
    When waterdrops have worn the stones of Troy,
    And blind oblivion swallowed cities up,
    And mighty states characterless are grated
    To dusty nothing, yet let memory
    From false to false among false maids in love
    Upbraid my falsehood.
    William Shakespeare (1564–1616)

    Satire is born of the cities it denounces.
    Mason Cooley (b. 1927)
