What If We Never Passed the Clean Air Act?

Fortyyears ago, the United States government passed theClean Air Acta federal law that regulates atmospheric emissions in order to protect the air we breathe from pollution. Without it, our world would look a whole lot different.

But what exactly does that mean?

Let me take you into an alternate reality, with the help of a report from our friends at Save on Energy: a reality in which air pollution levels have reached a new height, where impurities rule and air visibility is just about non-existent. You can find that full report here!

What would our cities look like? How would our lives be different?

The following graphics demonstrate how American citieswould look in a world without the Clean Air Act. The pollution levels were determined by calculatingconcentration of particles in the air (similar to China’s post polluted city, Xingtai), to visibility in miles.

Here’s the actual formula, for all your science aficionadosout there:

Adj. Max. Daily PM2.5 for Population = (US Pop. / Xingtai Pop.) * Max Daily PM2.5 for Xingtai

VL= (A * 10^3)/G

VL= Equivalent visual range.

A = 0.75 Adjusted for miles

G = Micrograms per cubic meter.

Here’s how Chicagowould look without the Clean Air Act:

What about Dallas? Houston?San Jose? Take a look!

What isAir Pollution?

According to the Save on Energy report, which gives a great definition, “Air pollution occurs when particulate matter, biological agents, or other harmful pollutants are introduced into the atmosphere, posing both an environmental and human health risk.” The World Health Organization (WHO) considers this to be just about any contaminant that “modifies the natural characteristics of the atmosphere.”

Pollutants like this can come through anything like industrial facilities, the burning of fossil fuels, vehicle exhaust, household fires and more. These pollutants can cause allergies and seriously detrimental diseases like lung cancer, chronic and acute respiratory disease, asthma, reduced fertility, neurological disorders and stroke.They also make their way into our foods, contaminating the fish and plants we eatthrough bioaccumulation,and cause acid rain. The Guardian suggests that air pollution kills approximately 3.3 million people every single yeara number that will double by 2050 if we don’t make some more serious changes to our pollution policies. That’s more than malaria and HIV/AIDScombined.

Did the Clean Air Act really make a difference?

Absolutely! Since 1973, when the Act was passed, the Clean Air Act has helped decrease surface ozone levels by 25 percent since 1980, reduced mercury emissions by 45 percent since 1990 and taken out more than half of the nitrogen oxide and sulfur dioxide responsible for acid rain since 1980. We can also thank the Clean Air Act for preventing the premature deaths of some 40,000 people, and millions more from contracting diseases like those listed above.

Thank goodness for proactivity!
