Part one. Reading

a. comprehension

Air pollution is not new. Natural air
pollution has been around for millions of years. Dust and a variety of gases
from forest fires, volcanoes, and decaying material in rivers, oceans, and
other bodies of water continually enter the atmosphere.

Sometimes this natural pollution can have
dramatic effects. For example, scientists believe that natural gas from plant
decay may have been one of the main causes of global climate change in the
past.

Of course, not all air pollution is
produced naturally. The atmosphere contains pollutants produced by humans, and
these man-made pollutants present a far more serious problem than natural air
pollution. Man-made pollutants are not only sometimes more harmful, but they
are usually concentrated over large cities where large
populations of people live and work and therefore cause serious health problems
to the inhabitants.
