English_Master December 27, 2014 No Comments
RIVER WATER POLLUTION IN INDIA Holy rivers have rather become a myth today. According to a report of the National Environment Engineering Research Institute (NEERI) all the fourteen big rivers of India are badly polluted. They cover 85 per cent of the surface flow of water in the country. The main pollutant of river water is industrial waste. River Jamuna in Delhi receives 6000kg of dissolved solids, 3000 kg of heavy metals and 200 kg of detergents every day. In its 48 km stretch around Delhi Yamuna gets polluted through 17 drains that bring   toxics, acids and a number of chemicals that affect the health of the river and consequently of all those who depend on it for drinking and bathing water. The Ganga starts getting polluted by chemicals from Rishikesh itself. It receives effluents from the Indian Drug and Pharmaceuticals Ltd (IDPL) and Bharat Heavy Electricals Ltd. (BHEL). The flow of toxic effluents including chemicals metallurgy and fertilizers to river periyar in Kerala is so great that the people living on its banks have a high incidence of skin diseases. Cauvery and Kapila in Karnataka are so polluted that in stretch of 10 km of the banks of Cauvery people suffer badly from skin diseases, boils and burning...

Essay on The Ozone Layer Depletion and Its Effects

Essay on The Ozone Layer Depletion and Its Effects

English_Master October 9, 2014 No Comments
ESSAY ON POLLUTION AND OZONE LAYER Ozone is a condensed form of Oxygen. It has three atoms of Oxygen instead of two and has a faint blue color with pungent odor.In industries it is used in deodorization, oxidation and bleaching and it is generated by a silent electric discharge in ordinary Oxygen. Thus it is useful in this way. It is very useful in saving life from sun radiation. It actually forms an umbrella over the earth. It is concentrated generally 30 km above the surface of earth. It is generated there by the interaction of high radiation of the sun on the oxygen in the atmosphere. Its concentration is only 10 ppm parts of air. Still it stops sun radiation to penetrate the earth. If there is a pollution of ozone i.e. if the ozone layer is disturbed the sun radiation would attack human life, animal and plant life. The ultra violet rays would eat all life on earth. A one percent reduction of ozone layer would mean 4 to 8 per cent increase of skin cancer among people having light colored skin. With an increase of 22 per cent cancer among men and 17 per cent women in Australia the Northern America was rather awake. Research in...

NUCLEAR PLANT POLLUTION : ESSAY TOPICS

English_Master October 9, 2014 No Comments
NUCLEAR PLANT POLLUTION Power starving world took shelter under the umbrella of nuclear plants. The idea sprang from the energy released by atom bombs. It is very difficult to have a nuclear war. The people became wiser. They channeled the atomic power into energy through atomic plants little knowing that the radiation from these plants would be a hazardous- even more- as that from ultra violet rays of the sun. Man cannot gain immunity from it. The nuclear plants are good only till they do not let radioactive fumes come out .It may come at intervals affecting animal world including man and poison food too. To remember a few-Ural mountains in Russia in 1957-58,UK in 1957,USA in 1961,Luceans Vad in Switzerland in 1969 ,Russia in 1974,USA again in 1975 and 1979,Tsuruga in Japan in1981,Buenos Aires in Argentina in1983,Oklahowa in USA in 1986,Three mile Island in USA in 1979 continuing up to 1987. Another study reported other 151 accidents in 14 countries between 1971 and 1984. A private body in USA reported 3000 accidents in Nuclear Power Projects in the USA in 1985 and 2,300 in 1984 besides 750 emergency shut downs in 1984. It looks rather strange that even after so many accidents polluting the world atmosphere there are...

NON CONVENTIONAL SOURCES OF ENERGY:ESSAY TOPICS

English_Master October 9, 2014 No Comments
NON CONVENTIONAL SOURCES OF ENERGY Wood has been the most common source of energy since the advent of human beings on the earth. Population being thin everywhere it seemed on everlasting source. Increase in population meant occupation of land for residential houses. That is how forests started depleting and disappearing too. Ti was not simply a loss in the potential source of energy but created environmental problem too. Since 18th century coal started replacing wood and was known as black gold. But the scientists knew that as the industries grew and the population increased coal reserves may last only for a hundred or two hundred years. The discovery of petrol of course proved a boon. But as the late Shah of Iran put it the stocks may last only by the first quarter of the 21st century. Nuclear or atomic energy started replacing these conventional sources of energy after the Second World War. Number of plants increased in the developed countries to an extend that by the eighties of the 20th century this too was considered as conventional source of energy. It is based on the principle of fission of a heavy atom of uranium or allied metals like plutonium that releases unlimited energy. It has two limitations. The...

Essay on Cause And Effects Of Noise Pollution

Essay Writing on NOISE POLLUTION EFFECTS

English_Master October 8, 2014 No Comments
NOISE POLLUTION Heat, light, electricity, water and sound, besides a number of things are provided by nature. If the five agents of nature are under control they are rather beneficial to an individual, a society or a nation. If they are in excess and go beyond the control of man or are misused by man they pollute the environment and affect the personal and social health. Excess of heat may decompose anything. To take a simple example the burning of coal in mills and factories the chimneys belch carbon dioxide, carbon monoxide and a number of other gases that pollute the atmosphere. Even the unburnt gas released in a heating process pollutes the environment. A combination of heat and light that emanates from the sun creates radio activity if the ozone layer grows thin. Electricity generated in the clouds may fall in the shape of lightening burning forest creating pollution. Pollution through dirty water is a common aspect. That sound too pollutes the environment may look funny to many. But it does. It may be sometimes imperceptible but no less harmful. Noise is directly related to man both in creation and experience. City roads are much affected with noise from automobiles, bands, mikes and the down town with quarrelling...

SHORT ESSAY ON GROUND WATER POLLUTION

English_Master August 12, 2014 No Comments
GROUND WATER POLLUTION If there are too many or too much salts in the underground water it may be brackish. One may not relish it. Still it may not be a health hazard. But of late it was found in Denmark that the infants, especially in rural agricultural areas suffered from methaemoglobinaenia. A research found that it was because of excess nitrates in the subsoil water. Further in vivo research revealed that transformation of nitrate and formation of nitroso compounds are responsible for stomach cancer. Further studies conducted by the agency for Environment Protection in Denmark revealed that the overall mean level of nitrate concentration in that country has trebled in the last 35 years or so. According to World Health organization even 10 p.p.m of nitrogen in the form of nitrates makes the water unfit for consumption by infants. With the results reasons too flew from Denmark to India. Though the Changes in ground water quality are still in a nascent stage the people in European Countries have become cautious about it. A study agricultural scientist of Punjab Agricultural University (PAU) revealed that increased and indiscriminate use of nitrogenous chemical fertilizers has been the cause of the malady. In the region of coarse textured irrigated farm land the...

Speech Topics on Benefits and Problems of DAMS

English_Master December 7, 2013 No Comments
DAMS – THE LIFE LINE OF A COUNTRY Water management is essential not only for the development but for the very existence of the people. It is because of non realization of this that in many developing countries floods and drought go side by side. In the year 2000 in certain areas of Gujarat water was to be transported by trains while certain areas of Orissa and West Bengal were reeling under floods. In certain areas of Bihar it rains heavily during monsoon. But immediately after the rainy season the farmer finds his fields dry. It just means that it is essential to store the water for future use .One may just be helpless for the floods. But these too can be controlled to some extend if the river is channeled towards big dams. Thus both for future use and for partially checking the floods big dams are necessary. For utilizing the rain water in sloppy areas like that of Bihar small dams are a must. It is rather exulting that while we had only 300 dams in 1947 we have 4300 big and small ones today. Thus the dam consciousness is gaining ground. During the last three centuries water requirement has increased 35 times. The annual consumption now...

Essay writing Topics on AUTOMOBILE POLLUTION / AIR POLLUTION

English_Master December 7, 2013 No Comments
IMPACTS OF AUTOMOBILE POLLUTION Before 1970 air and water pollution were considered serious problems. Noise and nuclear pollutions were added to these too – and ozone too. The smog that reduced the visibility in Malaysia and Mexico City and later the smog that engulfed the Los Angeles Valley in California in 1970 compelled the world to rise from the slumber. This photochemical smog was caused by the automobiles emitting different gases. Formerly only carbon dioxide was considered as the culprit. Carbon monoxide, hydrocarbons and nitrogen oxides were added to the list. Scientifically it was proved that the problem was severe as the sum of these three pollutants can create havoc. That is what we are observing throughout the world as automobiles are considered the most convenient source of travel. In 1999 the numbers of vehicles in India were estimated at 35 million. It was expected to be 53 million by the end of 2000.3.6 million vehicles are produced per year. The older vehicles emit more gases. This damage can hardly be rectified. In a few decades India may become not only a super vehicular country in the world but a super vehicle polluted country too. We have generally been talking about the levels and density of air pollution by...

Short Essay Writing Topic on AIR POLLUTION

English_Master December 7, 2013 No Comments
Essay Writing on AIR POLLUTION Scientific development in developed countries has gone as fast as population growth in underdeveloped countries. The two factors are equally responsible for pollution of different kinds. Increase in production means increase in factories, mills, petro chemical set ups and huge industrial complexes. Almost all these belch out smoke that pollutes the air inside the complex and of the neighboring area. Many factories manufacture deadly chemicals and fertilizers. The worst tragedy in the chemical industry took place in Bhopal in 1984. 45 tones of Methyl Isocynate(MIC) flew out of the Union Carbide Factory. The air was so polluted that 2500 people died the very day. Lakhs of people within an area of 40 km suffered from ailments of eyes, throat and lungs. Many such cases in small factories where only a few people are affected are never reported. With the increase in population we require more sources of transport. By 1994 more than 2 crore auto vehicles were registered in the country. Delhi was expected to have near about 25 lakh. In Delhi the 21st century begins with about 1 crore. These scooters, mopeds, cars, buses, and trucks increase the quantity of sulphur dioxide, other oxides, hydrocarbons and carbon monoxide in the atmosphere in cities...

Essay Writing on THE GUJARAT EARTHQUAKE

English_Master December 7, 2013 No Comments
A GREAT NATURAL CALAMITY ‘THE GUJARAT EARTHQUAKE’ “Saare jahan se accha” was silenced within a moment. There was no hue and cry – just a rumbling – the earth shook violently devouring 400 girls and boys who were marching towards the Town Hall in Anjar at 8.46 to celebrate the Republic Day on 26th January 2001 – The first Republic Day of the millennium. It was a festive occasion. There was fun, enjoyment, a general sense of well being and patriotism in the town. Students led the rally with teachers from various schools happily following them. Old men, young men, women and traders waved at the rally. Within a second all perished –three generations were under the huge debris. Three storied houses fell like nine pins. There was none to save the young ones – the blooming flowers of the nation. Nature offered them a mass grave- buried them with parents of many. The whole town of anjar 50 kms from Bhuj having a population of 65,000 known for its vegetable dyes and knives was now a mass grave. No house was served from the fury of nature. The death toll was estimated not less than 25,000.Even after the fifth day at least 1,000 people lay buried under the...
