ome human-created air pollutants form acids which come down either as
dry fallout, or as rain, snow, fog and cloud water. This fallout raises
the acidity level of lakes, streams and soils, injuring life in the water
and causing chemical inbalances in plants. Because the waters and soils
of the Sierra aren't able to neutralize acids very well, they are sensitive
to both wet and dry acidic fallout.
