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:
“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)
“The city is always recruited from the country. The men in cities who are the centres of energy, the driving-wheels of trade, politics or practical arts, and the women of beauty and genius, are the children or grandchildren of farmers, and are spending the energies which their fathers’ hardy, silent life accumulated in frosty furrows in poverty, necessity and darkness.”
—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)
