Pollution by LoneLy_heArt2010/04/12 02:38 Pollution of the environment is one of the most horrible ecological crisis to which we are subjected today. We know that 3 basic amenities for living organisms are air , land or soil & water. Sometimes in the past, these amenities were pure, undisturbed, uncontaminated and basically most hospitable for living organisms. But the situation is just the reverse today because progress in science and technology is also leading to pollution of environment & serious ecological imbalance which in the long run, may prove disastrous for mankind. "Environment pollution is the result of urban industrial technological revolution and speedy exploitation of every bit of natural resources". The craze of progress in agriculture, industry, transportation and technology is taken as the general criterion of devlopment of any nation. Such activities of man has created adverse effects on all living organisms in the biosphere.

LoneLy_heArt2010/08/10 02:36 The physical, chemical and biotic
factors which influence the
existence of an organism directly
comprises the environment and
if any direct or indirect
alternation of these factors
occur, it is called pollution, which
create a potential hazard to the
health, safety or welfare of living
species.
LoneLy_heArt2010/08/10 02:39 Air, water and land are the basic
amenities of life. But over
population and rapid
industrialization have created a
state of decadence in the
environment. Man has
continuously tampered with the
nature. As a result a threat to his
life has been increased, due to
the lack of healthy air and
potable water and the imbalance
established in the biosphere.
LoneLy_heArt2010/08/10 02:40 Earth is, perhaps, the only planet
endowed with an environment
and we all share it. One dy we
would pass it on to our future
generation as their legacy. But if
they will inherit such a polluted
environment, life will be misery
for them. Men has improved the
technologies and other means
necessary for higher production
of wealth and exploited nature
for his benefits, but without any
foresight as to what to
implications of his actions would
be. Indiscriminate
industrialization has resulted in
urban migration and slum
development, which in turn
resulted in degradation of
environment.
LoneLy_heArt2010/08/10 02:42 Before the advent of modern
civilization man lived and
flourished amidst the nice
balance of multiple biological
process. As the most intelligent
being on earth man has
constantly tampered with the
nature making use of his
inventive genius and disturbed
the ecological balance. Thus, air,
water and soil, all have got
polluted and posing threat to the
substance of mankind. The result
in numerous health problems.
LoneLy_heArt2010/08/10 02:43 Air pollution is due to the direct
implication of industrialization.
The chimneys of industries emit
smoke and vehicles have fumes,
which directly contribute to air
pollution. Any gaseous material
not considered a a normal
constituent of air or excess of
sulphur dioxide, carbon
monoxide, nitrogen dioxide, dust
etc. in air cause air pollution in
fact. Air pollution also occurs
when forests catch fire, rubber
plants are gutted or plastics are
burnt along with the household
garbage. This danger of pollution
has been aggravated today due
to atomic explosions in some
advanced countries. Some
hovering over the cities in they
early morning is also the result of
air pollution. The depletion of
ozone layer, which is very
essential for life to protect from
dangerous ultraviolet light, is also
due to air pollution and it may
result in skin diseases.
LoneLy_heArt2010/08/10 02:44 The emission of greenhouse
(GHGs) like carbon dioxide in
increased concentration has led
to climate changes. Although it
does not have toxic effect, it is
largely responsible for green
house effect and thus for global
warming.
LoneLy_heArt2010/08/10 02:45 Most of the air pollutants directly
affect the respiratory and
cardiovascular systems. Nitrogen
dioxide and ozone also effect the
respiratory system, irritate the
eyes, nose and throat and in
addition ozone can cause
headaches. Carbon monoxide is
able to displace oxygen in the
blood which in turn can result in
cardiovascular and neurological
effects. Lead affects bone
narrow, impairs liver and kidney
function, causes neurological
damage and limits metal
development in children.
LoneLy_heArt2010/08/10 02:46 Although earth is surrounded by
water in its three fourth area yet
drinking water has a scarcity. All
main source of portable water
like rivers, lakes, ponds, even
wells have been polluted by
various dangerous chemical and
biological wastes. The coagulated
mixture of dirt, sewage and
industrial waste pollutes the river
water on whose bank the
factories are established.
increased use of fertilizers and
insecticides also pollutes the
drinking water of ponds and
wells. The harmful fertilizers and
insectices even seep through the
earth and pollute the ground
water. The polluted water supply
results in epidemic like cholera,
jaundice and gastroenteritis etcs.
LoneLy_heArt2010/08/10 02:47 Soil is also being polluted in
various ways. Soil pollution
usually results from the disposal
of solid and semisolid wastes
from agricultural practices and
unsanitary habits. Excessive use
of pesticides, fertilizers and
manures resulting in both
biological and chemical
contamination. Rapid
industrialization and
urbanization has disposed
various solid and semisolid
wastes at different places
polluting soil as well as air and
water. Apart from this, direct
pollution of land by pathogenic
organisms is also a of major
importance. Thus, soil is getting
heavily polluted day by day by
hazardous materials and micro-
organisms which enter food
chain or water and are
consequently ingested by man.
As a result, there are numerous
health problems like dysentery,
cholera and paratyphoid fever.
Increased use of plastics,
politeness and other non-
degradable products has led to
the problem of their disposal.
LoneLy_heArt2010/08/10 02:48 Besides air, water and soil
pollution, today we face noise
pollution. The constant din and
bustle of city life, frequent
playing of loud speakers even in
odd hours, constant playing of
radios and televisions, ceaseless
loud sound of vehicles deafen us
in day time. Research has shown
that noise pollution is capable of
causing ulcers, abortions,
cardiovascular diseases and
hypertension besides several
mental disorders.
LoneLy_heArt2010/08/10 02:49 Food pollution is another
problem we have been facing
everyday. We suffer from several
diseases because of the polluted
food items that we take. After the
advent of nuclear weapons the
exposure level of ionizing
radiations has been increased
which is hazardous to people.
The ill-effects due to radioactive
pollution are cancers, genetic
damage and mutations leading
to abnormal birth.
LoneLy_heArt2010/08/10 02:50 Checking of environmental
pollution has been absolutely
necessary. if it is not checked, the
earth will become a graveyard. So
we must give due attention to
protect it from our own abuses.
We must have balanced and
planned industrial growth in
order to check thin pollution.
Towns and cities should be
planned very carefully and stress
should be given on planting of
more trees.
