Inverse Realities: Pittsburgh and Beijing, Yesterday, Today and Tomorrow

Today's post seeks to highlight, in brief, a simple connection between industrial production and air pollution.

In the 1940s, Pittsburgh was a global industrial leader in its steel mills and in the strength of its factory production and banking sector. The air pollution levels that accompanied the city during this industrial and economic boom ironically clouded the city so heavily, it had become an unhealthy and relatively undesirable place to live, as seen in the first photo below.

Pittsburgh, by the 1990s had seen a grand transformation from a heavy industry to a services-based economy, and likewise in much of the technologically advanced countries of the world. The city is now regularly ranked among the nicest to live in the United States for quality of life. The blue skies have largely returned from its industrial past to reveal one of the most unique skylines in the country, as appears in the second photo below. The question remains: where did its industry and pollution go?

In answer to the industry/pollution question, this blog post will highlight simply one aspect of an otherwise complex explanation. Inverse realities for Pittsburgh and Beijing in answer to the question can be shown in a few photographs.

The 1940s in Beijing, China were still a few years decades shy of the country's industrial boom from around 1980. Thus, as seen in the photo below, the blue skies are clear and can easily be viewed despite this early color photograph of downtown Beijing in 1946.

Fast forward to 2014, Beijing experienced an extended smog crisis that engulfed the city after decades of unchecked heavy industrial growth. Much like the 1940s photo of industrial Pittsburgh, downtown Beijing is shrouded in heavy and unhealthy smog, also blocking what could be an otherwise sunny day for the Chinese capital.

Finally, the connection between heavy industry and stagnating air pollution in cities appears for itself. Critics have been quick to point the finger at China for the amount of pollution it puts into the atmosphere each year, but they forget that the pollution-causing industry had been exported to the East from the already developed West (US, Canada, Europe, Japan). China's economic development has grown so fast in just the past 30 years that one may ask the question, in another 30 years, what cities or countries will shoulder the blame for accepting exported industry, jobs - and environmentally damaging pollution?
