Man, as part of the terrestrial biological community, is living in the lowest layer of the air masses. His well-being not only depends on temperature, air humidity, and barometric pressure, but also on the chemical contents of the air. Human activities are causing a rise of the proportion of optically and chemically active trace gasses; this in turn is going to change the radiation balance at the earth's surface (greenhouse effect). Man-caused emission of SO2 and NOx is acidifying the troposphere and is leading to increased deposition into soils. In urban centers, smog frequency is increasing at an alarming rate. The changes in the chemical composition of the air affect plant communities; and, as stressors, they destabilize entire ecosystems. Only a drastical cutback of emissions promises relief against further deterioration, the motivation for that not only being the ecological threat, but also a not any more calculable economical damage.
