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 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)
“We are in danger ... of making our cities places where business goes on but where life, in its real sense, is lost.”
—Hubert H. Humphrey (1911–1978)
“1st Murderer. Where’s thy conscience now?...
2nd Murderer. I’ll not meddle with it. It makes a man a coward.... It fills a man full of obstacles. It made me once restore a purse of gold that by chance I found. It beggars any man that keeps it. It is turned out of towns and cities for a dangerous thing, and every man that means to live well endeavors to trust to himself and live without it.”
—William Shakespeare (1564–1616)
