ENVIRONMENTAL PROBLEMS AND SOLUTIONS
Environmental pollution refers to the introduction of harmful pollutants into the
environment. It has a hazardous effect on the natural world and on the activities of living
beings.
The major types of environmental pollution are air pollution, water pollution, noise
pollution, thermal pollution, soil pollution and light pollution.
Deforestation and hazardous gaseous emissions also leads to environmental
pollution. During the last 10 years, the world has witnessed severe rise in environmental
pollution.
We all live on planet earth, which is the only planet known to have an environment,
where air and water
are two basic things that sustain life. Without air and water the
earth would be like the other planets – no man, no animals, no plants. The biosphere in
which living beings have their sustenance has oxygen, nitrogen, carbon dioxide, argon
and water vapor. All these are well balanced to ensure and help a healthy growth of life
in the animal world. This balance does not only help the lifecycles of animals and
plants, but it also creates the perennial sources of minerals and energies without which
the human civilization of today could not be built. It is for this balance that the human
life and other forms of existence have flourished on earth for so many thousands of
years.
But man, as the most intelligent animal, never stopped being inquisitive, nor was he
content with the bounties of nature. His quest for knowledge and search for security
succeeded in exploring newer and wider avenues of mysteries that remained baffling so
long. Man’s excursions into the darkest regions of mysteries laid foundations for the
stupendous civilization, for the conquests of men had ensured their domination in their
world and gave them a key to control all the forces in nature.
With the dawn of the age of science and technology, there has been huge growth
and development of human potentials. And, it is here that man first began losing control
and became prisoner of his own creations.
Sources and Causes
The sources and causes of environmental pollution includes the following:
Industrial activities: The industries all over the world that brought prosperity
and affluence, made inroads in the biosphere and disturbed the ecological
balances. The pall of smoke, the swirling gases, industrial effluents and the fallout
of scientific experiments became constant health hazards, polluting and
contaminating both air and water. The improper disposal of industrial wastes are
the sources of soil and water
pollution.
Vehicles: The smoke emitted by vehicles using petrol and diesel and the
cooking coal also pollutes the environment. The multiplication of vehicles, emitting
black smoke that, being free and unfettered, spreads out and mixes with the air
we breathe. The harmful smoke of these vehicles causes air pollution. Further, the
sounds produced by these vehicles produces causes noisepollution.
Rapid urbanization and industrialization: The urbanization and the rapid
growth of industrialization are causing through environmental pollution the
greatest harm to the plant life, which in turn causing harm to the animal kingdom
and the human lives.
Population overgrowth: Due to the increase in population, particularly in
developing countries, there has been surge in demand for basic food, occupation
and shelter. The world has witnessed massive deforestation to expand absorb the
growing population and their demands.
Effect
Environmental pollution has negatively affected the life of both humanbeings and
animals. Almost all of our gains in the fields of industrial progress, science and
technology had so far been realized at the cost of our health. Even our flora and fauna
were found to be threatened with extinction.
All this really leaves us wondering if all our achievements and industrial civilization really
help us climb the peaks of prosperity or simply take us down the blind alleys of
adversity. It is not only in India, but all over the world – even in Europe and U.S.A. – that
the question is being raised whether all is well with our industrial growth and progress in
the field of science and technology. Many crusaders against environmental pollution are
vehemently protesting against the indiscriminate violations committed daily in the name
of development.
The environmental pollution is not caused by the fallout from nuclear tests or industries
alone. The smoke left behind the automobiles and other vehicular traffic, the increasing
use of synthetic detergents, nitrogen fertilizers and insecticides contaminate both air
and water.
The water we drink the vegetables are all contaminated today. As a result of this
contamination our world is afflicted with a quite a number of incurable diseases.
Nothing in this world is immune, no life is safe and the future of this world is
bleak.
The factories are mostly built in populated areas and the smokeemitting vehicles
ply through the congested areas. Besides causing immense disturbances, there
are increasing case of pulmonary tuberculosis and thrombosis and various sorts of
brain and heart complications.
Airpollution may cause severe lungsdiseases, asthma, braindisorder diseases,
etc.
Soilpollution may have negative effect on farm output ratio. It can also
contaminate the ground water.
Noisepollution have negative effects
also cause deafness, tiredness, and mental losses.
on hearing or auditory sense organs. It can
The heat generated by industries and vehicles causes thermal pollution by
raising the environmental temperature of the nearby areas.
The birth of mills and factories is the result of the growth of industry in this machine
predominated age. As long as they will be there, they must emit smoke, pollute the air
and hasten our end by slowpoisoning.
The worst industrial environment tragedy occurred at Bhopal on December 3, 1984 as a
result of toxic and poisonous leakage of methyl isocyanate (MIC) gas from a multi
national Union Carbide pesticides manufacturing plant. Over 2000 people including
woman and children were killed, and hundreds were severely hurt.
Solution
What then is the remedy? There surely cannot be any radical solution, for the existing
factories cannot be bodily lifted to a place far from the populated zone. However, the
following attempts can be made to solve the problem of environmental pollution.
The Government can at least see that future factories are set up at a distant
place, an industrial complex far away from the township.
Researcher may find out how to avoid harmful smoke from running vehicles.
Deforestation should be stopped and Forestry should be developed.
Discharge of Factory wastes in rivers should be banned so as to make the river
water free from pollution.
Initiatives
1. The UN Conference on Human Environment was convened to study the
profound changes in the relationship between man and his environment in the
wake of modern scientific and technological developments.
2. The World Health Organization also set up an international network for the
monitoring and study of air pollution on a global scale and for devising possible
remedies. Conclusion
We can very well notice the abnormal behaviour of the seasons – the cycle developing
clogs in its wheels; and the worried experts fear that the disturbed balance in the
biosphere has assumed such serious proportion that very soon our world would be
uninhabitable like Hiroshima of 1945. But it is heartening to find the entire world aware
of the menace. Some of the advanced countries have already taken some measures to
meet it. If we fail to restore the ecological balance right now, it would be too late
tomorrow.
