The argument that policies to address environmental problems such as global warming will harm economic progress is not new:

London's Historic "Pea-Soupers", by David Urbinato, EPA Journal: ...Shakespeare, whose witches in Macbeth chant, "fair is foul, and foul is fair: Hover through the fog and filthy air."

Smog in London predates Shakespeare by four centuries. Until the 12th century, most Londoners burned wood for fuel. But as the city grew and the forests shrank, wood became scarce and increasingly expensive. Large deposits of "sea-coal" off the northeast coast provided a cheap alternative. Soon, Londoners were burning the soft, bituminous coal to heat their homes and fuel their factories. Sea-coal was plentiful, but it didn't burn efficiently. A lot of its energy was spent making smoke, not heat. Coal smoke drifting through thousands of London chimneys combined with clean natural fog to make smog. If the weather conditions were right, it would last for days.

Early on, no one had the scientific tools to correlate smog with adverse health effects, but complaints about the smoky air as an annoyance date back to at least 1272, when King Edward I, on the urging of important noblemen and clerics, banned the burning of sea-coal. Anyone caught burning or selling the stuff was to be tortured or executed. The first offender caught was summarily put to death. This deterred nobody. Of necessity, citizens continued to burn sea-coal in violation of the law, which required the burning of wood few could afford.

Following Edward, Richard III (1377-1399) and Henry V (1413-1422) also tried to curb the use of sea-coal, as did a number of non-royal crusaders. In 1661, John Evelyn, a noted diarist of the day, wrote his anticoal treatise FUMIFUNGIUM: or the Inconvenience of the Aer and Smoake of London Dissipated, in which he pleaded with the King and Parliament to do something about the burning of coal in London. "And what is all this, but that Hellish and dismall Cloud of SEACOALE?" he wrote, "so universally mixed with the otherwise wholesome and excellent Aer, that her Inhabitants breathe nothing but an impure and thick Mist accompanied with a fuliginous and filthy vapour..."

Laws and treatises failed to stop citizens from burning coal, however. Too many people burned it and there were no real alternatives. Anthracite coal was much cleaner but too expensive...

At the turn of the century, cries to reduce the smoke faced a tough opponent. Coal was fueling the industrial revolution. To be against coal burning was to be against progress. "Progress" won out.

Not until the 1950s, when a four-day fog in 1952 killed roughly 4,000 Londoners was any real reform passed...
