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:

    What care though rival cities soar
    Along the stormy coast,
    Penn’s town, New York, Baltimore,
    If Boston knew the most!
    Ralph Waldo Emerson (1803–1882)

    In great cities men are brought together by the desire of gain. They are not in a state of co-operation, but of isolation, as to the making of fortunes; and for all the rest they are careless of neighbours. Christianity teaches us to love our neighbour as ourself; modern society acknowledges no neighbour.
    Benjamin Disraeli (1804–1881)

    Over the tree-tops I float thee a song,
    Over the rising and sinking waves, over the myriad fields and the
    prairies wide,
    Over the dense-packed cities all and the teeming wharves and ways,
    I float this carol with joy, with joy to thee, O death,
    Walt Whitman (1819–1892)
