A dark and polluted Pittsburgh in the early 1940s

This gallery of pictures of a dark and polluted Pittsburgh in the early 1940s is fascinating:

In 1941, influenced by a similar policy introduced in St. Louis four years earlier, the city of Pittsburgh passed a law designed to reduce coal production in pursuit of cleaner air. Not willing to cripple such an important part of the local economy, it promised to clean the air by using treated local coal. The new policy ended up not being fully enacted until after World War II.

While the idea was a small step in the right direction, other factors ultimately helped improve Pittsburgh’s notorious air quality. Natural gas was piped into the city. Regional railroad companies switched from coal to diesel locomotives. And, ultimately, the collapse of the iron and steel production industries in the 1980s led to rapidly improved air quality leading into the 21st century.

Control of coal smoke made it possible to clean soot-covered buildings and to re-plant hillsides, helping provide the city a look it could hardly envision in the depths of its industrial heyday.

I’ve seen some of these pictures before and they are hard to believe: how did people survive in a city that looked like this? Despite some of the debate over environmental regulations today, I think everyone could agree that Pittsburgh and other cities have benefited from having cleaner air.

This is also a reminder of how far some communities will go for their signature industries. Industry may bring in money and provide jobs but it is often not without downsides.

Six reasons for living in the country versus in cities

The Yahoo Green blog provides a list of “six amazing things city dwellers miss out on.” Here are the six items on the list: stars, fresh air, peace and quiet, greenery, sounds of nature, and animals and wildlife.

It is interesting to think how many cities have created spaces where city dwellers can get glimpses of these things. Many large cities have large parks (think Central Park or Grant Park or the Golden Gate National Recreational Area) where some of these things are possible. However, as this blog suggests, seeing the stars even in the suburbs or thinking about city wildlife versus country wildlife is quite different.

To have all six of these things, how far would this blog suggest one has to move from the city? And for most Americans, how would these six amenities rate against the amenities that cities offer?
