Cities
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:
“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)
“Such poverty as we have today in all our great cities degrades the poor, and infects with its degradation the whole neighborhood in which they live. And whatever can degrade a neighborhood can degrade a country and a continent and finally the whole civilized world, which is only a large neighborhood.”
—George Bernard Shaw (1856–1950)
“If I be false, or swerve a hair from truth,
When time is old and hath forgot itself,
When waterdrops have worn the stones of Troy,
And blind oblivion swallowed cities up,
And mighty states characterless are grated
To dusty nothing, yet let memory
From false to false among false maids in love
Upbraid my falsehood.”
—William Shakespeare (1564–1616)
