Last week, I was in Pittsburgh, PA to serve as a Mentor at a Climate Reality Project training event. Having never been in that part of the country before, I spent a few extra days to explore the area. The overall experience felt like a road trip through US environmental history and was a great reminder that large-scale changes are possible, especially in this era of climate policy backpedaling.
First stop: Donora, PA. This Pittsburgh suburb was the site of the “Killer Smog of 1948”. As the longtime home of the Donora Zinc Works Factory and the American Steel and Wire Plant, smoke-filled skies were not unusual here in the early part of the 20th century. In October 1948, however, the air turned deadly. An inversion layer, a weather phenomenon where the temperature in the atmosphere increases with height instead of decreasing, trapped emissions from the factories. The sulfuric acid, nitrogen dioxide, fluorine, and other poisonous gases created a thick, yellowish smog. It hung over the area until the weather pattern changed five days later. As a result, twenty-six people died and thousands of others became ill.
This tragedy garnered national attention and spurred federal regulations on air pollution. In 1955, Congress provided funding for pollution research and later passed the Clean Air Act of 1963. In 1970, the EPA was created and Congress passed the Clean Air Act Amendments, which established national air quality standards.
Donora is proud of their role in this change in national environmental policy. Outside of their local Historical Society/Smog Museum is a sign that says “Clean Air Started Here”.
Another highlight of this trip was Cuyahoga Valley National Park in northeastern Ohio. Established as a National Recreation Area in 1974 and upgraded to a National Park in 2000, it reclaimed and now preserves the natural landscape along twenty-two miles of the Cuyahoga River between Akron and Cleveland, OH. While relatively small, the river is an icon of American environmental history.
Starting in the late 1800s, the river became highly industrialized. For more than a century, the steel mills and factories that lined its banks dumped untreated waste directly into the river. The Cuyahoga became so polluted that it caught on fire thirteen times.
The last time was June 22, 1969, when sparks from a passing train ignited the oil and debris floating in the water. This fire, while not the largest or deadliest in the river’s history, caught the attention of Time Magazine and became national news. Appearing in their August 1 issue, the article described the Cuyahoga as a river that “oozes rather than flows”.
During the late 19th and early 20th century, river fires were common and seen as the price of industrial progress and prosperity. By the 1960’s, however, that way of thinking was starting to change. The country was becoming more environmentally aware and the Cuyahoga River fire put a national spotlight on the need to protect waterways from industrial pollution. The event helped to galvanize the Water Quality Improvement Act of 1970 and the Clean Water Act of 1972.
In the years since, the Cuyahoga River has made an amazing comeback. Bald Eagles – a symbolic emblem of this country – have returned to fish its waters and nest along its banks. In 1998, it was designated as an American Heritage River to recognize its historical significance.
Today, our environmental challenge is the carbon pollution that drives climate change. Its solution, as with conservation issues in the past, lies with policy adjustments. While these types of large changes can sometimes seem impossible, history reminds us that they are not. All that is required is the will to act. As Nelson Mandela once said, “It always seems impossible until it’s done”.
