Control of Pollution in the Environment:
According to scientists and philosophers man is considered as the
major factor in disturbing the natural balance of the universe. Man
interferes intentionally or unintentionally in the earth’s
ecosystems by impairing its perfect order and precise sequence. But
it seems that man has cut off his nose to spite his face and he now
is the victim. Grave dangers are manifested in pollution of the air,
water, soil, outer space and others, as well as the irrational
exploitation of the environment’s resources, and inconsistent
distribution of human settlements. All these factors have lead to
different problems, all of which are marked by a disturbance to the
earth’s natural balance.
Urban populations are concentrated in towns usually emerging close
to one or more natural resources (water, oil, fuel, sea, etc.) which
create a marked disturbance in the existing natural balance. This
imbalance is mainly attributed to the increasing waste disposal
(human or industrial), exploitation of resources and density in
population. It must be admitted that man’s claims on the
environment have overstepped the mark in many cases, creating a
disruption to the natural balance of various bio- and eco-systems
all over the world. This irresponsible behavior has lead to a
depletion in the atmosphere and this poses the greatest threat
worldwide.
There are countless examples of disturbances to the environment.
Forests have been removed, deserts have been encroached upon, and
many species of plants and animals have disappeared throughout the
world. All these affect the macro- environment because it is an
integrated whole.
The climate has changed and is in fact still changing due to unwise
human activities. There are, however, natural and non-human induced
reasons for the climate changes that should not be ignored, such as
the pattern of the earth’s rotation around the sun and volcanic
explosions. The over-use of wood, excessive removal of pasture land,
and deforestation which destroys and eradicates magnitudes of the
earth’s vegetation all play a role in raising the earth’s
absorption of the sun. In addition, there is the high use of energy
over and above man’s need, which raises the temperature of the
atmosphere and thus affecting climate.
The over-use of non-renewable resources - oil, coal and natural gas
- leads to a continuous increase in carbon dioxide in the
atmosphere, which, in turn, raises the temperature.
The ozone layer has been further exposed to destruction as a result
of the exhausts of planes flying in the higher altitudes, as well as
gases and fumes expelled from nitrogenous fertilizers and
atmospheric pollution from factories. The danger of the depletion of
the ozone can only be imagined when we realize to what extent the
earth will be exposed to more carcinogenic rays. As a result the
climate will altered worldwide, destroying the dense forests,
reducing agricultural output and killing most living creatures
except for insects which can withstand the ultraviolet rays.
Man’s disruption to the natural balance of forests leads to
various problems that are reflected on him as well as other
creatures on earth. Soil is washed away, humus shrinks, rainwater
runs in torrents, temperatures fluctuate, high and severe winds
become more common and drought spreads globally.
In addition to toxins expelled into the air and waste pumped into
the water by factories, nuclear explosions, radioactive pollution,
there is the problem of man-made chemical pesticides used to control
pests which are injurious to the agricultural or animal wealth.
Pesticides and other toxins interfere with the ecosystems and have
destructive consequences that appear in all layers of the
atmosphere, water, soil, and outer space. In attempting to eradicate
or control these creatures which compete with man for survival and
natural resources, man has designed deadly poison which he breathes
in or drinks and eats through crops, meat and dairy produce
The corrupters of the earth, whether those who deny God, practice
injustice or go against the universal laws, are referred to by the
following Quranic verses.
“There is the type of man whose speech about this world’s life
may dazzle thee, and he calls The God (Allah) to witness about what
is in his heart: yet is he the most contentious of enemies? When he
turns his back, his aim everywhere is to spread mischief through the
earth and destroy crops and cattle. But Allah loves not mischiefâ€
(Al-Baqarah: verses 204 and 205)
An incidence occurred prior to these verses being revealed. A man
named Al-Akhnas Ibn Shuriq came to the Prophet Muhammad (peace be
upon him) to embrace Islam, but as he turned to leave, he happened
to pass by a pasture and grazing animals. He set it alight and
killed the cattle. The verses were sent down as a sign of Divine
disapproval.
This incident recurs over history on a wider scale involving
millions of people throughout the earth. The natural wealth
deposited by Allah for the benefit of mankind has been spoiled.
Selfishness and aggression has overcome mankind, as they have become
corrupters of earth, the surrounding atmosphere and neighboring
outer space. Allah the Almighty says:
“Mischief has appeared on the land and sea, because of (the need)
that the hands of man have earned, that (Allah) may give them a
taste of some of their deeds: in order that they may turn back (from
evil).†(Ar-Rum: verse 41)
Mischief on the land and sea is inflicted by man’s unwary
interference with the natural laws and environmental systems that
are ultimately against his own interests. Environment pollution,
which is tantamount to the disruption of natural balance, is the
main form of corruption on earth.
As Allah created man on earth, he decreed that man should preserve
this habitat. He gave man the right to invest in it and benefit from
it. He enjoined upon man not to cause mischief anywhere. He
addresses whoever may think of disturbing the natural balance, the
earthly equilibrium, or inflicting injustice.
“Seek not mischief in the land, for Allah loves not those who do
mischief.†(Al-Qasas: verse 77)
Islam and its Ummah is moderate, where its people do not consider
nature and cosmic objects as deities, but at the same time do not
tamper with or spoil them. The relationship between the Muslim and
the universe is one of harmonious benefit and use. When Allah takes
an oath by some creatures, he draws attention to the fact that man
should recognize their value and take care of them.
“By the sun and his splendor. By the moon as it follows him. By
the day as it shows up (the sun’s) glory. By the night as it
conceals it. By the firmament and its structure. By the earth and
its expanse.â€(Ash-Shams: verses 1-6)
“By the night as it conceals (the light). By the day as it appears
in glory. By the creation of male and female. “(Al-Lail: verses
1-3)
“I call to witness the siting of the stars. And that is indeed a
mighty adjuration if you but-knew, That this is indeed a Quran most
honorable. “(Al-Waqi`ah: verse 75-77)
With such an adjuration and call for revering other creatures and
aspects of His creation, Allah urges man to jettison bashfulness
towards them because such an attitude does not yield progress or
civilization. Removing the beauty of these creatures and failing to
draw the benefit from them causes man to neither gain in morals nor
lead him to progress or civilization.
Controlling Noise Pollution:
Noise leads to environmental, psychological and physical harms.
There is evidence that inhabitants of large cities suffer from
fatigue and psychosomatic disorders due to constant exposure to
noise. Although noise has been considered harmful or at least
unpleasant, noise pollution has been regarded as the worst negative
effect of the industrial era, and a characteristic of industrially
developed societies. Yet, little attention has been given to it, as
pollutants of the air or the water have tended to take precedence.
This is due to the following factors: noise is caused by a variety
of sources everywhere. It is not easily targeted; the effect of
noise disappears as it stops, without leaving a lasting trace on the
environment, although continuous exposure to noise leads to certain
disorders, as explained below; noise is a domestic or local
environmental pollutant. Unlike water and air, its effects do not
spread from one country to another.
What is the definition of noise?
According the Encyclopedia Americana, it is the pressure that harms
man and other animals. Sir. A. Wilson Committee of Noise Affairs
defines it as the sound that is undesirable to the receiver. A
recent definition of noise is that it is a form of environmental
pollution that is not less dangerous than the man-made toxins.
Noise is measured by “phon†and “decibel†(dB) - the former
being the unit of sound pitch, the latter being the unit of its
pressure or impact. At 1000 Hertz, phon = 100dB, at 3500 Hertz: 100
phon=89 dB, and at 50 Hertz: 100 phon= 110db. The decibel is the
minimum of the difference between two sounds detectable by the human
ear. At zero, the sound is very low. It rises gradually until 130 dB
at which degree it becomes painful, Scientists have determined the
noise values of some sounds in nature and measured them in dB:
- Natural breathing -10dB;
- Rush of tree leaves in breeze-50 dB;
- Traffic in a crowded street - 70 dB;
- A large water fall- 90 dB;
- A nearby machinegun - 130 dB
- Aircraft taking off-140dB;
- A rocket in lift-off - 175 dB.
Sounds are divided into the following categories: very quiet, quiet,
audible, medium, high, and noisy. The last category is painful at
130 dB. There are several sources producing this noise:
-Some natural sources like thunder, storms, clashing waves, dogs
barking, wind, waterfalls, avalanches, fires, etc.
-Man-made noise coming from agricultural and industrial equipment,
transportation etc, and even household tools, machines and
instruments.
In major cities one kind of noise is known as the “ambient or
background noiseâ€, which means everything one may hear at home, in
the street and at work, created by planes - particularly jets -
traffic, street vendors, children playing, radios and other audio
sets, washing machines, factory machinery, workshops, live bands,
etc.
The dangerous effects of noise
Noise has seriously bad effects on the human ear.
But does it have physical, psychological or social effects?
1) The auditory damage:
The level of noise in major cities and urban centers has become so
serious that it will be a danger to public health if it continues at
the present rate. Although noise has existed around man for millions
of years, its medical dangers have only been recognized since 1930,
when homes were used in different kinds of vehicles running inside
and between cities. One of the earliest studies on the biological
effects of noise was that sponsored by US Naval research office
under the supervision of the University of Chicago, and published in
early December in 1953. It indicated that US marines who worked in
noisy conditions suffered from excessive fatigue, occasional nausea,
and loss of libido.
Reports filed by research committees in the following decades
indicated that more than 20 million people were suffering from
noise-induced hearing loss in the US alone, as noise was the most
prominent of the environmental pollutants. A study concluded in 1968
by the Federal Council of Science and Technology (specific committee
for the environment) warned that about 4.5 million workers might
apply for compensation for loss of hearing.
Excessive noise damages thousands of cells in the
ear leading to an immediate loss of hearing, which happens in
explosions and wars. Constant exposure to noise may lead to a
gradual damage of the cells and a gradual loss of hearing. Deafness
may even result from a bullet fired or an explosion. In the former
case, deafness results from auditory waves, whereas in the second it
results from pressure waves. The pathological disorders in that case
involve the outer ear, as the drum congests and may be pierced due
to mechanical changes. It also involves the middle ear, as the parts
may be torn and loose, then bleed and an aqueous fluid can
subsequently appear in it.
Deafness means a weakening in the hearing. It may be temporary,
partial or complete. The human ear can endure sounds safely up to 60
dB, but may be injured by more intensive sounds that affect it
constantly or temporarily. Deafness happens at the following stages:
Weakness in hearing for a
short period that may disappear after some minutes or hours
(with occasional loud noises in factories, workshops or crowded
places).
Constant weakness, due to
which one fails to hear a quiet talking (usually resulting from
continuous daily exposure to high noise).
Complete permanent deafness
(resulting from a continuous daily exposure to very high noise
like explosions and bombs).
Records on workers in Sweden indicate that many
are exposed to loud machinery noise daily. About 5000 people
suffered hearing loss in 1973 and the figure rose to 16,000 in 1977.
An official report of the Environment Affairs Council in US issued
in 1970 indicated that about 16 million industrial workers faced the
risk of losing their jobs due to the weakness in their hearing
abilities.
2) Non-Auditory Damage:
The Fetus: The fetus floats on fluids that protect
it from jerking movements, but barely from noise. It can hear
internal sounds (the mother’s heart beat, the movement of the
intestines, and the air in her lungs) as well as external sounds
(the mother’s voice and any surrounding sounds or voices). Studies
indicate that the fetus experiences muscular spasms if the mother is
exposed to excessive noise. It develops a response similar to the
post-delivery - “Motor reflex actionâ€. The heartbeat of the
fetus, after its sixth month, accelerates if the mother is exposed
to extreme noise. Research conducted on animal fetuses, when human
cases are difficult to study, reveal bone deformities in the fetuses
whose mothers were exposed to noise that led to a hormone imbalance.
The Nervous System, the Circulatory System and the
Endocrine Glands:
Extreme noise affects the nervous system, and
creates electric pulses that travel through the nerve fibers to the
brain cortex, the highest functional region in the brain. The cells
of the cortex are stimulated to identify incoming noise. Sub-cortex
regions are also affected, particularly the reticular formation (a
lump of cells at the base of the brain) which is directly related to
the higher layers of the brain up to the meninges, as well as the
spinal cord. Consequently, the autonomic nervous system,
particularly the sympathetic system is stimulated. The latter
controls the circulatory system (the heart and the blood vessels),
the function of the endocrine glands and the digestive system -
particularly the stomach. Disorders of varied intensity occur
according to the intensity and duration of the noise, and are
reflected in several physical disorders.
Medical studies also indicate that noise leads to
higher rates of cholesterol and tri-glyceride in the blood, which
blocks the blood vessels and leads to heart attacks and heart
failure. Excessive production of the corticosteroid hormones is
related to heart attacks, and is caused by the effect of noise on
the adrenal gland.
3) Psychological and Social Damage:
Man - and animals - behaves properly when in a
stable, normal mental state, according to the observations of
psycho-sociologist Charles Kort and some of his colleagues. The
study showed 2567 cases of people who live in noisy areas and heavy
traffic in Holland. Psychological studies on industrial workers
indicate that those who are subject to high-density noise suffer
from irritability, dizziness, headaches, moodiness and anxiety.
Children are naturally more affected by noise than
adults. The mental capacities of school pupils are influenced by the
surrounding noise, for example near airports where they feel
distracted and frustrated. Children under 7 are the most sensitive
to noise, as they become annoyed and often cry if they hear a sudden
loud sound.
Soft music calms the nerves, whereas the loud
music and jerky movements performed by young people in nightclubs
leads to severe tension due to the effect of amplifiers, not to
mention the auditory harms indicated earlier.
Calmness relaxes the nerves, noise irritates them: Concentration and
deep contemplation need a calm atmosphere to allow the person to be
creative. The noise from a wedding down the street to me has
compelled me to stop at this point until the street is calm once
again.
Generally, life in a big city like Cairo is full
of noise. An intellectual can hardly be creative in such an
atmosphere. Like all major cities, the roaring of machines and the
clinging of steel conceal the humming of bees and the twittering of
birds. Chimneys and discharged toxic smokes replace the gardens and
parks that gave sweet smells. Noise also disturbs those sleeping,
leading to muscular contractions, so that one wakes up feeling tired
rather than fresh.
Now, in the Glorious Quran, are the verses that
call to avoid noise, such as the following:
“Neither speak thy prayer aloud, nor speak it in
a low tone, but seek a middle course between.†(Al-Israa: verse
110)
“O you who believe, raise not your voices above
the voice of the Prophet. Nor speak aloud to him in talk, as you may
speak aloud to one another, lest your deeds become void and you
perceive not. Those that lower their voices in the presence of the
apostle of Allah – their hearts has Allah tested for piety: for
them is forgiveness and a great Reward.†(Al-Hujurat: verse 2,3).
“And be moderate in thy pace, and lower thy
voice, for the harshest of sounds without doubt is the braying of
the ass .†(Luqman: verse 19)
The Quran and the Sunnah enjoin quietude and
self-control as well as caring for the feelings of others, and
avoiding anything that can hurt them: even a loud voice. The first
verse orders Muslims not to voice their prayer too loud, nor in an
inaudible voice. They should seek a middle course in the
“jahriyah†(in Arabic, articulated so as to be heard) in prayer
and not the “sirriyah†(in Arabic; sub-vocalized). In the second
verse, the Muslims are asked to lower their voices in the presence
of Prophet Muhammad (peace be upon him). The injunction is both
particular and general. Noise must generally be avoided particularly
in solemn gatherings. The last verse carries Luqman’s exhortations
to his son, and approves of them. The exhortations of previous
prophets and apostles that are mentioned in the Quran are meant to
be a source of advice to Muslims. In Luqman’s exhortation, the son
is advised to lower his voice, and avoid speaking unnecessarily
loud. To instill this message, he uses the metaphor of the braying
ass, which implies that any pollutant of the environment or anything
that is conducive to public discomfort is just as unpleasant and
hateful.
At the time of Prophet (peace be upon him) his
Companions were considering how to call for the five daily prayers
at their appointed time. Suggestions included blowing a horn,
drumming or ringing of bells, but all were turned down by Prophet
Muhammad (peace be upon him). Allah revealed to one of the
Companions a procedure in calling the prayer. He proposed it to
Prophet who approved of it. But the Prophet chose Bilal to do so.
In conclusion, it should be noted that the noise
pervading some so-called Islamic countries has nothing to do with
Islam. Unless the teachings, principles and the code of behavior
approved by Islam are adhered to, one can not pretend to be a real
Muslim.
Pollution in the Natural Environment and
Ethical Environment
Pollution is any quantitative or qualitative change in the animate
of inanimate components that cannot be accommodated by the
ecological systems without disturbing their balance. Before the
industrial revolution there were no problems with pollution as the
natural cycles of ecological systems could easily accommodate and
recycle the waste of the different human activities.
Pollution as a quantitative change only rises as the rates increase
of some natural components in the environment, such as the rise in
carbon dioxide due to massive forest fires. Quantitative change may
also occur as a result of a slight addition to a certain material in
a sensitive area, such as oil spillages from tankers due to
accidents or defects. It also occurs as a result of introducing
lethal or toxic materials, even in their normal concentrations, such
a mercury, carbon oxides and radioactive material.
Qualitative pollution results from the addition of synthetic or
industrial compounds foreign to the natural ecological systems,
which accumulate in water, air, food, or soil. Foremost among these
are insecticides and herbicides. Pesticides containing chlorine,
like DDT, have proven to be the most dangerous compound.
Pollution is one form of corruption (“fasal†in Arabic)
mentioned in the Glorious Quran eight times. Counting the
derivations of the word “fasal†mentioned elsewhere in the Quran
raises the number to 49. “Fasal†involves physical corruption
like disrupting the environmental phenomena and the contents of the
universe (water, soil, food) by foolish human interference in the
natural balance created by Allah the Almighty, Who did so wisely,
perfectly and infallibly to fit the life of all creatures.
Water pollution in general means polluting water
streams, wells, rivers, seas, rain and underground water in such a
way that makes it unfit for man, animals, plants, or the sea and
ocean creatures. Air pollution involves the discharge of gases,
smoke and fumes (the solid, liquid and gaseous forms of matter) into
the air surrounding living creatures, and the change of its natural
composition. This leads ultimately to the unsuitability of the
habitat, contrary to what Allah willed for His creatures.
Physiological, economic and biological damages are, in fact,
devastating to man, animals, plants and other creatures.
It is highly portentous that pollution reached places hitherto
unthinkable. The rate of lead in snow in Greenland was found to be
higher than the rate some decades ago. This is a peculiar phenomenon
as the island is almost deserted. It has no cars or factories.
Finally, it was concluded that this high rate was attributed to the
winds, which carried the vapor, smoke and gases from European
factories to such remote territories.
Soil pollution is a form of corruption of the natural properties and
compositions created by Allah to serve vegetation and the
preservation of pure rainwater. Air pollutants can affect the water
and soil also, since air, water and soil are systems that are
closely interrelated.
Any form of reverting the straight-forwardness enjoined in the
saying of Muhammad: “Say believe in Allah, then be straight
forward,†pollutes life in this world. The necessities of life are
to be obtained honestly. Theft, bribery, embezzlement, and such
things pollute what one does for a living. Islam defines the
relationship between people and the society, and between them and
the vast universe on the bases of love, amity, peace, cooperation,
fraternity, and the rejection of grievances, envy, hatred and hard
feelings. All forms of hatred, envy, spoiling the relationships
between people, terrorizing the peaceful, usurping land and
property, looting and plundering, or involving the world in
destructive wars was are pollution of the security and stability of
life. Marriage is the proper form of satisfying the sexual activity.
Adultery, fornication or homosexuality and such things are a
pollution of the souls and the purity of genealogies.
The moral environment is the mental state of an individual, a group,
or a country, within which the international acts of the individuals
occur. It may be so wide as to include several countries or
continents if their populations belong to one moral code and live
according to a comprehensive moral ground.
This environment may be good or evil. A good moral environmental
encompasses the individuals of a society who live by certain morals
like tolerance, patience, endurance, generosity, chivalry, courage,
justice, charity, humility, pride and high energy and others. An
evil moral environment is one pervaded by low morals like treachery,
lying, cheating, trickery, panic, roughness, permissiveness, spouse
insolence, indecency, slander, hypocrisy, arrogance, despair, etc.
Islam commends kindness and calls for spreading virtues among
people. It lays down, the foundations for a healthy moral
environment. The Messenger of Allah, Muhammad Ibn Abdullah (peace be
upon him) is the epitome of this code. The Quran describes him in
may ways.
The Prophet was enjoined to observe good manners and behaviour. The
order applies to all Muslims:
“Repel (evil) with what is belief: Then will he between whom and
thee was haired become as it were thy friend and intimate.â€
(Fussilat: verse 34)
The Messenger of Allah says that he has been sent to perfect the
virtuous morals. This means that the previous heavenly messenger
came to call for the worship of Allah alone and then for the
virtues. Muhammad (peace be upon him) came to complete the framework
of virtues.
