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:
“The cities of the world are concentric, isomorphic, synchronic. Only one exists and you are always in the same one. It’s the effect of their permanent revolution, their intense circulation, their instantaneous magnetism.”
—Jean Baudrillard (b. 1929)
“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)
“Books may be burned and cities sacked, but truth like the yearning for freedom, lives in the hearts of humble men and women. The ultimate victory, the ultimate victory of tomorrow is with democracy; and true democracy with education, for no people in all the world can be kept eternally ignorant or eternally enslaved.”
—Franklin D. Roosevelt (1882–1945)
