Why do you think lichens are not commonly found in cities where are pollution is big problem?
Lichens are sensitive to air pollution, particularly sulfur dioxide and nitrogen oxides, which can inhibit their growth and survival. In urban areas with high levels of pollution, the harsh chemical environment can damage their delicate structures and interfere with their ability to photosynthesize. Additionally, the lack of suitable substrates and the disturbance of natural habitats in cities further limit their presence. As a result, lichens are often more abundant in cleaner, less disturbed environments.
What else can I help you with?
Where is air pollution worst?
In cities which have not taken steps to limit the problem - at the moment some of the Chinese cities have this problem.
Lichens do not grow around cities because pollutants such as sulfur dioxide quickly destroy a lichen's?
That's not always true, some lichens are indeed sensitive to pollutants such as sulphur dioxide and will therefore not grow in highly polluted areas. However some lichens thrive on certain pollutants and therefore will grow very well in highly polluted areas (cities).
How lichens indicate pollution?
lichens are sensitive to sulfur dioxide, they are biological indicators. The cleaner the air the more lichens will grow. Therefore if there are houses right by a road, if you look on the roof there would be less lichens as there would be more sulfur dioxide in the air because of pollution. Hope this helps By Troy Flynn

Is air pollution just a recent development?
Actually air pollution has been less of a problem than ever. The people who suffer worst from air pollution are people who burn biomass (wood, food waste, dung) inside without proper ventilation. In cities outdoor air pollution was a problem which was made worse by industrialization. In London smog was common and deadly smogs happened every decade or so. Air pollution in most US cities peaked in the 1950's and is far less of a problem than when the first Earth Day was held in 1971.
