POLLUTION

Environmental pollution is defined as the introduction of
contaminants into the natural environment that cause adverse changes. It is the presence in or introduction into
the environment of a substance or thing that has harmful or poisonous
effects.
This brings to mind Barry Commoner’s Second Law of Ecology
which states that: “Everything must go somewhere.”… That there are no actual “wastes”
in nature and that there is no way that anything could be thrown away. Therefore, anything that exists could only be
converted to other forms of matter or energy but could not be totally discarded
to render it non-existent. There is an
old Filipino adage that says: “Ang basurang itinapon, babalik at babalik sa iyo!” (Any waste thrown away will eventually return
to you!)
Pollutants can take the form of chemical substances or
energy that are often classified as “point source” or “nonpoint source”
pollution. There are also natural
processes in our ecosystem that cause pollution, such as: (a) Volcanic eruptions; (b) Decomposition of
biotic elements; (c) Microbial fermentation; etc. There really isn’t much we could do about
these natural causes since they are part of the system. The more worrisome pollutants, however, are
those we (ourselves) introduce into our environment such as the synthetic
chemicals and materials that take a very long time to dissolve. Human population or the meteoric increase in
human population can also be considered a pollutant and a pollution scenario. This worldview is maintained in the context
of man’s dependence on the environment and his consumption/utilization of natural
resources as means to survive. Having
stated these, it is not hard to imagine that the troublesome environmental pollutants
are from anthropogenic or man-made sources or causes.
An interesting form of pollution is “noise”. Noise (defined as: a sound, especially one
that is loud or unpleasant or causes disturbance and irritation) is largely
considered as a pollutant because it also has harmful effects, although more
psychological than physiological, to humans.
Discussing the sources of environmental pollution will allow
us to understand their dire effects to the present and future generations and
the environment in general… and the need to do something positive about
it. As Barry Commoner stated, pollution
is here to stay. We could only lessen
the introduction of additional pollutants to lessen environmental pollution.
Just my little thoughts…
