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:
“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)
“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)
“Again and again I am brought up against it, and again and again I resist it: I don’t want to believe it, even though it is almost palpable: the vast majority lack an intellectual conscience; indeed, it often seems to me that to demand such a thing is to be in the most populous cities as solitary as in the desert.”
—Friedrich Nietzsche (1844–1900)
