However, when more people share the drive, emissions per person are reduced, making driving more environmentally friendly than flying. But if you are driving cross-country solo, you are better off taking to the skies.
What does smog smell like?
To scientists, blaming industrial plants didn’t make sense anyway. Smog from burning coal—common in Pittsburgh and London—didn’t normally damage crops. Furthermore, as chemical instruments tycoon Arnold Beckman pointed out, smog in those places had a sulfurous smell (like a match) and appeared yellow or black.
What causes industrial smog?
Industrial smog forms when smoke and sulfur emissions, from coal burning, combine with fog, under the right conditions. While the release of large quantities of air pollutants can form industrial smog, other factors have an important role in the severity of a smog outbreak.
Why is smog a problem?
Why is it harmful? When inhaled, smog irritates our airways, increasing our risk of serious heart and lung diseases. These health risks are why many cities monitor smog levels. On a high ozone-alert day, for example, your eyes and throat may burn, and you may cough and wheeze.
Is smog good or bad for the environment?
Smog affects much more than just human lives; it also has a large impact on the surrounding physical environment. Ozone and PM in particular cause damaging effects: Ozone can damage plant cells and inhibit their growth, reducing the amount of carbon dioxide that they take in during photosynthesis.
How is smog made?
The Formation of Smog
Ground-level ozone is formed when vehicle emissions containing nitrogen oxides (primarily from vehicle exhaust) and volatile organic compounds (from paints, solvents, and fuel evaporation) interact in the presence of sunlight.
