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:
“Just as language has no longer anything in common with the thing it names, so the movements of most of the people who live in cities have lost their connexion with the earth; they hang, as it were, in the air, hover in all directions, and find no place where they can settle.”
—Rainer Maria Rilke (1875–1926)
“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)
“The cities are the principal home and seat of the human group. They are the coral colony for Man, the collective being.”
—Alfred Döblin (1878–1957)
