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:

    Such poverty as we have today in all our great cities degrades the poor, and infects with its degradation the whole neighborhood in which they live. And whatever can degrade a neighborhood can degrade a country and a continent and finally the whole civilized world, which is only a large neighborhood.
    George Bernard Shaw (1856–1950)

    Not like the brazen giant of Greek fame,
    With conquering limbs astride from land to land,
    Here at our sea-washed, sunset gates shall stand
    A mighty woman with a torch, whose flame
    Is the imprisoned lightning, and her name
    Mother of Exiles. From her beacon-hand
    Glows world-wide welcome; her mild eyes command
    The air-bridged harbor that twin cities frame.
    Emma Lazarus (1849–1887)

    Today as in the time of Pliny and Columella, the hyacinth flourishes in Wales, the periwinkle in Illyria, the daisy on the ruins of Numantia; while around them cities have changed their masters and their names, collided and smashed, disappeared into nothingness, their peaceful generations have crossed down the ages as fresh and smiling as on the days of battle.
    Edgar Quinet (1803–1875)
