The phenomenon of pollution of the environment has
increased in many countries of the world to the extent
that it threatens the continuity and survival of the human
race.
The main sources of pollution are : remains of
combustion, refuse of industry, human wastes, pesticides,
fertilizers, and radioactive substances.
All of these give
off products into biosphere and so living organisms are
affected in one way or another.
In addition, sound
pollution caused by factories and huge aircrafts, as well
as noise in the cities and bad habits of some people, all
cause harm to man.
Traces of pollutants may remain in the biosphere for a
long time.
They may also be transmitted to other places which
means that their harm is not restricted to their sources,
but may extend to other places.
Pollution of the environment includes the change in
its characteristics due to both quantitative and qualitative
changes affecting that environment.
