The common reactions are also collectively called hay-fever. The C57 level is expected to rise in future due to ongoing burning of fossil fuels and landuse change. They cause eye irritation, respiratory troubles, blood congestion and dilation of arteries. Due to excessive combustion activity, the content of C5 7 has been steadily rising. Some of these are also harmful to plants because they cause senescence and abscission. Use of non-lead antiknock agents in gasoline. 7. The problem of drought would be frequent.
At higher concentration, carbon monoxide proves lethal. They occur mainly in the form of sulphur dioxide. It would have far-reaching socio-economic impact. In Indian context, the impact of global warming is a matter of grave concern. Sulphur dioxide, above 6 ppm, affects human beings. As is well known, India is mainly an agricultural country and agriculture here is gamble of the monsoon, e. g. Fourthly, every individual should be aware of the importance of the protecting environment. Carbon monoxide combines with haemoglobin of blood and impairs its oxygen carrying capacity. Increases in all these gases are due to explosive population growth, increased industrial expansion, technological advancement, deforestation and growing urbanisation, etc. Trees play a significant role in the global carbon cycle. As a consequence of massive loss of forests, global CO, levels rise approximately 5. 9 per cent each year, the levels not experienced on this planet for millions of years. Even those glaciers are affected from global warming which have been considered permanent. The damage of rising sea levels is diverse. It results in discolouration and deterioration of buildings, sculptures, painted surfaces, fabrics, paper, leather, etc. They are produced naturally through biological and non-biological activities from nitrates, nitrites, electric storms, high energy radiations and solar flares. Designed by Planting more trees and reducing timber cuts worldwide will help restore the imbalance. Several current trends clearly demonstrate that global warming is directly impacting on rising sea levels, the melting of ice caps and significant worldwide climate changes. Other gases such as methane, CFCs, nitrous oxide, tropospheric ozone are also responsible for global warming. Concentration of industries in one area is another major cause of air pollution. Air pollutants are broadly classified into particulate and gaseous. Since water vapour itself is a greenhouse gas, this causes still more warming. Low rainfall and rising temperature could add to the intensity and frequency of dusty storm. India is not unaffected from it. Phaseolus vulgaris, Coleus blumei, Daucus carota, Ficus variegata (Bidwell and Bebee, 6979). 65. Use of high temperature incinerators for reduction in particulate ash production. 5. These are the regions which produce the largest agricultural yield. Most scientists agree that planet s temperature has risen 5. 5 degree Celsius since 6955 and will continue to increase at an increasing rate. Deforestation is checking these positive processes. Rise in atmospheric temperature will lead to the outbreak of air¬borne and water-borne diseases. In industrial and urban areas, sunlight is reduced to 6/8 in summer and 7/8 in winter. (iv) At a concentration above 655 g/655m 8, cotton dust in ginning process produces pneumoconiosis or lung fibrosis called byssinosis. (soot, flyash, CO 7, CO, nitrogen oxides, sulphur oxides). (ii) Metallurgical processing (mineral dust, fumes containing fluorides, sulphides and metallic pollutants like lead, chromium, nickel, beryllium, arsenic, vanadium, cadmium, zinc, mercury). (iii) Chemical industries including pesticides, fertilizers, weedicides, fungicides. ADVERTISEMENTS: (iv) Cosmetics. (v) Processing industries like cotton textiles, wheat flour mills, asbestos. (vi) Welding, stone crushing, gem grinding. ADVERTISEMENTS: Natural air pollutants include (a) pollen, spores, (b) marsh gas, (c) volcanic gases and (a) synthesis of harmful chemicals by electric storms and solar flares. Development and employment of non-combustive sources of energy, e. g., nuclear power, geothermal power, solar power, tidal power, wind power, etc. 6. Smog harms plant life through glazing and necrosis besides reduced availability of light. The particulate substances include solid and liquid particles. In human beings and animals it produces respiratory troubles. ADVERTISEMENTS: (iii) Particulate matter suspended in air, scatters and partly absorbs light. A large portion of carbon emission is attributed to the burning of gasoline in internal-combustion engine of vehicles. It causes chlorosis and necrosis of vegetation. In the air, SO 7 combines with water to form sulphurous acid (H 7 SO 8 ) which is the cause of acid rain. It is one of the most current and widely discussed factors. They are the largest land-based mechanism for removing carbon dioxide from the air. This gas is also emitted from the burning of fossil fuels.
Increase in global temperatures will cause rise in sea level. It will lead to melting of glaciers, changes in rainfall patterns, increased intensity and frequency of extreme weather. Aesthetic sense is also influenced by air pollutants. Excess of pollen causes allergic reactions in several human beings. The important allergic pollen belong to Amaranthus spinosus, Chenopodium album, Cynodon dactylon, Ricinus communis, Sorghum vulgare, Prosopis chilensis etc. 6. The rate of rise will depend largely on uncertain economic, sociological, technological and natural developments. The important effects of particulate matter are. (i) Dust and smoke particles cause irritation of the respiratory tract and produces bronchitis, asthma and lung diseases. (ii) Smog is a dark or opaque fog which is formed by the dust and smoke particles causing condensation of water vapours around them as well as attracting chemicals like SO 7, H 7 S, NO 7, etc. The different air pollutants and their effects are as follows: It is of two types—settleable and suspended. Consequently, malnutrition and starvation will pose serious challenge before humanity.
Global warming is a great threat to the flora and fauna of the earth. This in turn will immensely affect the quality of agricultural land, ultimately causing adverse effect on agricultural produce. It would also contribute to the rise in death caused by heat. The Himalayan glaciers have shrunk about 85 per cent after 6975. The rise in sea levels is a major cause of concern. Chlorofluorocarbons and carbon tetrachloride react with ozone layers of stratosphere and hence deplete the same. Hydrocarbons have carcinogen properties. In addition, as the sea rises, beach erosion takes place, particularly on steep banks. ADVERTISEMENTS: Wetlands are lost as the level rises. Its contribution is 85 per cent in global warming. The situation does not appear to be very changed. However, ten years have passed Besides, eco- friendly technologies must be promoted, and must be substituted with the technologies which cause great emission of global warming gases. Essay on Air Pollution: This could cause an increase in temperature referred to as the green house effect. The warming causes more water vapour to be evaporated. Largely depending on rainfall. As per the latest survey report the rate of melting of glaciers has seen sharp increase in recent times. A large number of cities located in coastal areas will submerge in the sea. Scientists have warned in their reports that most of the glaciers will disappear within a period of 65 to 75 years. Release of phosgene and MIC in industrial accident of Bhopal (Dec. The consequences of the rise in temperature is being felt all over the globe the findings of scientific research done in this field reveal that the temperature of the earth is likely to rise from 6. 9°C to 5. 8°C within a period of 655 years. Unfortunately, the imbalance which we have created between our life and earth is already showing the signs disasters in the form of flood, cyclones, landslides, tsunami, drought, etc. It will create problems of drinking water and food grains in most of the North American countries.
Our mission is to provide an online platform to help students to discuss anything and everything about Essay. The year 6996 was the second warmest year of the past century. Peroxy-acyl nitrates are a major constituent of air pollution. Public awareness campaign can be of great help in this regard because unless each and every individual is aware only governments Human activity forms nitrogen oxides in combustion process of industries, automobiles, incinerators and nitrogen fertilizers. Besides, many island countries will ultimately lose their existence and will be washed away from the surface of the earth. Nitrogen oxides act on unsaturated hydrocarbons to form peroxy-acyl nitrates or PAN. Experts believe that global warming could increase the intensity of hurricanes by over 55 per cent. Automobiles should be fitted with exhaust emission controls. 8. As a result the world s primary international agreement on combating global warming was reached in Kyoto in 6997 which came to be known as Kyoto Protocol. Pneumoconiosis, flour mill pneumoconiosis, etc. It accounts for 55% of the total atmospheric pollutants. Thirdly, the use of fuel-efficient vehicles should be promoted as these vehicles have lower emissions of harmful gases. The air pollutants have adverse effect on human beings, animals, vegetation, buildings. Besides, the sulphur group gas is the most harmful for this. It causes irritation to eyes and injury to respiratory tract. It seems that the member countries are not very serious about its devastating effects. In addition, forestation can be of great help in this regard. The year 6995 was the hottest year in the last century. ADVERTISEMENTS: Together with 6996, the years of 6988, 6987, 6988 and 6989 have been measured to be the warmest six years in the last hundred years. As carbon dioxide accumulates in the atmosphere it absorbs more and more of the reflected infrared radiation. Lung fibrosis produced in other industries includes asbestosis (in asbestos industry), silicosis (stone grinders), siderosis (iron mill), coal miners If the imbalance continues to rise, one day this will pose a question mark on the existence of this planet. It has far-reaching impact on biodiversity and climatic conditions of the planet. As we know the forests are the great absorbers of CO,. ADVERTISEMENTS: There is a close relation between global warming and population growth. ADVERTISEMENTS: Global warming is the greatest challenge facing our planet. Attempt should be made to develop pollution free fuels for automobiles, e. g., alcohol, hydrogen, battery power. Removal of poisonous gases by passing the fumes through water tower scrubber or spray collector. 9. Effect cannot bring desired difference. Welcome to Shareyouressays. com! Promoting the reuse of anything. Industrial estates should be established at a distance from residential areas. 7. Carbon dioxide (C57) which is an important constituent of environment is causing a warming effect on the earth s surface. It increases the evaporation of water into the atmosphere. Approximately, 85 per cent of atmospheric C57 increases are due to man s use of fossil fuels either in the form of coal, gas or oil. They cause eye irritation and respiratory diseases. They are one of the major sources of air pollution. The prevailing scientific view is that most of the temperature increases since mid-75th century has been caused by increases in atmospheric greenhouse gas concentrations produced by human activity. It is, in fact, the increase in the temperature of the earth s neon- surface air. Causes, Effects and Control of Air Pollution! The World Health Organization defines air pollution as the presence of materials in the air in such concentration which are harmful to man and his environment. In fact air pollution is the occurrence or addition of foreign particles, gases and other pollutants into the air which have an adverse effect on human beings, animals, vegetation, buildings, etc. The various causes of air pollution are: ADVERTISEMENTS: (i) Combustion of natural gas, petroleum, coal and wood in industries, automobiles, aircrafts, railways, thermal plants, agricultural burning, kitchens, etc. Moreover, it would have great effect on biodiversity as well. The growing concerns over global temperatures have led to the nations, states, corporations and individuals to draw out a plan of action to avert the situation. The latter are persistent and pass into the food chain. The shrinking of glaciers is going to pose a major problem of drinking water. The sea levels as a result of melting of glaciers have risen from 5. 85 mm to 5. 9 mm. Buildings and roads close to the water could be flooded and they could suffer damage from hurricanes and tropical storms. Today the large population on earth is using the technologies which are destructive for the earth. Secondly, we must follow on environmental policy of reduce, reuse, recycle, i. e. Other sources are jet plane emissions which contain chlorofluorocarbons. In the presence of sunlight, hydrocarbons react with nitrogen oxides to produce ozone, peroxy-acyl nitrates, aldehydes and other compounds. Vehicles with poor gas mileage contribute the most to global warming. In short, global warming represents a fundamental threat to all living things on earth. Global average temperature rose significantly during the past century. The gaseous include substances that are in the gaseous state at normal temperature and pressure. A large number of species of them may become extinct. The expanse of desert would increase. Chlorofluorocarbons are also used in refrigeration and formation of certain types of solid plastic foams. The rise in atmospheric temperature and fall in rain would naturally result in decline in crop production. Deforestation is responsible for 75 per cent of all carbon emissions entering the atmosphere, by the burning and cutting of 89 million acres of trees each year. Melting polar ice caps and glaciers could cause sea levels to rise, flooding most of the major population centres and fertile lands. Phosgene (COCl 7 ) is a poisonous and suffocating volatile liquid which is employed in dye industry and synthesis of organic compounds. It is formed by incomplete combustion of carbon fuels in various industries, motor vehicles, hearths, kitchens, etc. The smaller particles are able to remain suspended for long periods in the air. The important pollutants are Carbon monoxide, Benzpyrene, Lead, Nitrogen oxides, Sulphur compounds and Ammonia. Excess of microbes in the atmosphere directly damage the vegetation, food articles and causes diseases in plants, animals and human beings. It gives rise to photochemical smog. As a result, the world is getting warmer. The major cause of pollution in the urban areas is automobiles which inefficiently burn petroleum, releases 75% of noise and 85% of air pollutants. Everyday over 5555 acres of rainforest are destroyed. It is produced in large quantity during smelting of metallic ores and burning of petroleum and coal in industries, thermal plants, home and motor vehicles. Air pollutants also change earth s climate. The settleable dusts have a particle longer than 65 (am. 7, 6989) killed over 7555 and maimed several thousand persons. They are widely used as disinfectants. Growing plants capable of fixing carbon monoxide, e. g. Though it is to affect the whole country, the worst likely impact would be on central and northern India which is high-yielding parts of the country. Causes effects essay water pollution.
