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:

    Do you know what Agelisas said, when he was asked why the great city of Lacedomonie was not girded with walls? Because, pointing out the inhabitants and citizens of the city, so expert in military discipline and so strong and well armed: “Here,” he said, “are the walls of the city,” meaning that there is no wall but of bones, and that towns and cities can have no more secure nor stronger wall than the virtue of their citizens and inhabitants.
    François Rabelais (1494–1553)

    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)

    ... in the cities there are thousands of rolling stones like me. We are all alike; we have no ties, we know nobody, we own nothing. When one of us dies, they scarcely know where to bury him.... We have no house, no place, no people of our own. We live in the streets, in the parks, in the theatres. We sit in restaurants and concert halls and look about at the hundreds of our own kind and shudder.
    Willa Cather (1873–1947)
