Universal  environmental pollution, including greenhouse gas emissions and acid  deposition, as well as water pollution and waste management is  deliberated as global public health problems, which should be examined  from manifold perspectives such as social, economic, legislation, and  environmental engineering systems, as well as lifestyle habits helping  health promotion and reinforcing environmental systems to repel  adulteration (Loux, 2011). It is observed that the problems of  environmental pollution is intense in the developing world, where  traditional sources of pollution such as industrial emissions, poor  sanitation, insufficient waste management, polluted water supplies and  exposures to indoor air pollution from biomass fuels affect humans  (Samet, 2001). Recently, modern pollutants have emerged which are  associated with traffic congestion and the use of modern chemicals in  the home, in food, for water treatment and for pest control.<br> Air Pollution has emerged as growing global issue among  environmentalists and researchers especially in developed countries  since the decade of 1960 (Kan, 2009). It affects human and animal lives,  natural ecosystems and the man-made environment. The main pollutants  found in the air people breathe include, particulate matter, PAHs, lead,  ground-level ozone, heavy metals, sulphur dioxide, benzene, carbon  monoxide and nitrogen dioxide (European Public Health Alliance, 2009).  Air pollution in urban areas has numerous health impact such as a  shorter lifespan for city inhabitants (Progressive Insurance, 2005). <\/p>\n\n\n\n<p>Air pollution is also responsible for climate change due to the \nenhanced greenhouse effect, acid rain, and the depletion of the ozone \nlayer that constitute important global environmental problems. Mishra \nstated that fast growth in urban population, increasing \nindustrialization, and rising demands for energy and motor vehicles are \nthe deteriorating air pollution levels (2003). He further said that \nother factors, such as poor environmental ruling, less efficient \ntechnology of production, jammed roads, and age and poor maintenance of \nautomobiles also increase pollution level. It is established that air \npollution is caused of ill health and death by natural and man-made \nsources. Major man-made sources of ambient air pollution include tobacco\n smoke, combustion of solid fuels for cooking, heating, home cleaning \nagents, insecticides industries, automobiles, power generation, poor \nenvironmental regulation, less efficient technology of production, \ncongested roads, and age and poor maintenance of cars and other \nautomobiles. The natural sources include furnaces and waste disposals, \nforest and agricultural fires (European Public Health Alliance, 2009). \nAir pollution occurs both outdoors and indoors and is caused by human \nactivities and natural mechanisms. Outdoor air pollution is described as\n the discharge of numerous air pollutants in to the atmosphere, in \nconcentrations that threaten the health of living organisms or upset the\n function of the environment as a system leading to human health damages\n in various ways. Indoor air pollution is defined as the amount of \nchemical, biological and physical contaminants in the air inside a \nbuilding. Indoor air pollution is more dangerous as compared to outdoor \nair pollution. Some of indoor air pollutant sources in houses including \nbuilding materials, pressed wood products and furniture, central heating\n and cooling systems, several personal care or household cleaning \nproducts, painting colours, solvents, heating or cooking appliances \n(stoves, wood and gas burning fireplaces, gas heaters), tobacco smoke, \noffice machines and other products used in daily activities (EPA, 2007).\n<\/p>\n\n\n\n<p>\n<strong>Consequences of Air Pollution: <\/strong><br>\nAir pollution cause many health issues. It is found that CO2 is a good \ntransmitter of sunlight, but it also partially restricts infrared \nradiation going back from the earth into space, which produces the \ngreenhouse effect that prevents a drastic cooling of the Earth during \nthe night.  Increasing the amount of CO2 in the atmosphere strengthens \nthis effect and is expected to result in a warming of the Earth&#8217;s \nsurface.\nAir pollution has harmful impact on plant life. Sulphur di oxide is \nconsidered as most harmful pollutant (Rao, 1989). \n\n<\/p>\n\n\n\n<p><strong>Effect of pollutant on plants (Source: Rao, 1989)<\/strong><br>\n<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Effect-of-pollutant-on-plants.png\" alt=\"Environmental Pollution and Degradation\" title=\"\"><\/figure>\n\n\n\n<p>Air pollution monitoring is very necessary to control pollution. \nThese techniques collect data by scientists to enable them to make \ninformed decisions to manage overall quality of environment. <br>\n<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Air-pollution-monitoring.png\" alt=\"Air Pollution Monitoring\" title=\"\"><\/figure>\n\n\n\n<p><strong>Air pollution monitoring and source categorization (Source: Bhola, et, al., 2010)<\/strong><br>\n\n<\/p>\n\n\n\n<p>\n<strong>Water pollution:<\/strong> Water pollution is also a matter of concern for \nhuman life. Polluted water comprises of Industrial discharged wastes, \nsewage water, rain water pollution (Ashraf et al, 2010). Water can also \nbe polluted by agriculture or households cause damage to human health or\n the environment. (European Public Health Alliance, 2009). This water \npollution adversely impacts the health and quality of soils and \nvegetation (Carter, 1985). Pollutants in water include a wide range of \nchemicals, pathogens, and physical chemistry or sensory changes. Many of\n the chemical substances are toxic or even carcinogenic. Pathogens can \nobviously produce waterborne diseases in either human or animal hosts. \nThe effects of water pollution are major cause of death for humans at \nglobal scale. Furthermore, water pollution affects oceans, lakes, \nrivers, and drinking water (Scipeeps, 2009). A drinking water contained a\n fluoride content ranging from 5.26 to 26.32 milligrams per litre and \nthis is too high as compared to the World Health Organization\ufffds standard\n of 0.6 to 1.7 milligram per litre (Rizvi, 2000). It has been found that\n Paper and pulp mills consume large amount of water and discharge liquid\n and solid waste products into the environment. The liquid waste is \nusually high in biological oxygen demand, suspended solids, and \nchlorinated organic compounds such as dioxins (World Bank, 1999).\n<\/p>\n\n\n\n<p><strong>Types of water pollution: <\/strong><br><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Types-of-water-pollution.png\" alt=\"Water Pollution\" title=\"\"><\/figure>\n\n\n\n<p>\n<strong>Treatment of water pollution:<\/strong> There are many ways by which water \npollution can be treated such as industrial treatment, denitrification, \nseptic tank, and ozone waste water treatment. Before raw sewage can be \ncarefully released back into the environment, it must be treated \nproperly in a water treatment plant. In a water treatment plant, sewage \ngoes through a number of chambers and chemical processes to reduce the \namount and toxicity of the waste. Denitrification is an ecological \napproach to avert the leaching of nitrates in soil, and stops ground \nwater pollution with nutrients. Septic tanks treat sewage at the place \nwhere it is located and used to treat sewage from an individual \nbuilding. Untreated sewage from a property flows into the septic tank \nand the solids are separated from the liquid. Environmentalists use \nBiological processes to degrade the solid matter. Another method to \ntreat water pollution is well known Ozone wastewater treatment. An ozone\n generator break down pollutants in the water source. The generators \nconvert oxygen into ozone using Ultraviolet radiation and Electric \ndischarge field. There are numerous advantages of ozone to treat \nwastewater such as this technique kills bacteria successfully, oxidizes \nsubstances such as iron and sulphur. There are some drawbacks of \nadopting ozone to treat wastewater such as it requires energy in the \nform of electricity, cost money and cannot work when the power is lost \nand cannot remove dissolved minerals and salts. \n\n<\/p>\n\n\n\n<p><strong>Water pollution treatment<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Water-pollution-treatment.png\" alt=\"Environmental Pollution\" title=\"\"><\/figure>\n\n\n\n<p>\n<strong>Land\/ Solid waste Pollution:<\/strong> This type of pollution also shake \nenvironment.  Inadequate management of solid waste is one of the main \ncauses of environmental pollution (Kimani, 2007). Land pollution is one \nof the main forms of environmental calamity in current situation (Khan, \n2004). Causes of Land Pollution include Mining and quarrying, Sewage \nwaste, Household Garbage and Industrial Waste. Consequences of Land \nPollutants are dangerous such as extermination of wild life. In land \npollution, acid rain kills trees and other plants and vegetation that \nprovides food and shelter is destroyed. It can seriously disturb the \nbalance of nature, and, in extreme cases, can cause human mortalities. \nPesticides can damage crops; kill vegetation and poison birds, animals, \nand fish. Most pesticides kill or damage life forms other than those \nintended. To prevent Land Pollution, it is advised that more and more \nland should be brought under farming. Trees should be planted \neverywhere. Waste matter should be disposed immediately and avoid \ndrilling the Land for more underground water. People must avoid using \nmore chemical fertilizers and Pesticides.<br>\nNoise pollution, soil pollution and light pollution also harm the \nenvironment at an alarming rate. Causes of Noise Pollution include \naircraft noise, noise of cars, buses, and trucks, vehicle horns, \nloudspeakers, and industry noise, as well as high-intensity sonar \neffects which are extremely harmful for the environment, noise from \nconstruction and civil engineering works. Extreme noise pollution occurs\n due to technical advancement and the motor vehicle, which is \nresponsible for about ninety percent of all undesirable noise \ninternationally. Effects of Noise Pollution are Hearing Loss, High Blood\n Pressure, Stress, Sleep Disturbance, Colour Blindness. To Avoid Noise \nPollution, the Government should ensure the new machines that should be \nnoise proof. Air ports must be away from residential area. Do not sound \nhorn symbol is to be in school roads. Soil pollution is described as the\n impurity of soil of a particular region. Soil pollution mainly is a \nresult of penetration of damaging pesticides and insecticides, which \ndeteriorate the soil quality, thus making it contaminated and unfit for \nuse later. Main causes of soil pollution include Industrial wastes such \nas harmful gases and chemicals, agricultural pesticides, fertilizers and\n insecticides, ignorance towards soil management and related systems, \nunfavourable and harmful irrigation practices, improper septic system \nand management and maintenance of the same, leakages from sanitary \nsewage, acid rains, when fumes released from industries get mixed with \nrains, fuel leakages from automobiles, that get washed away due to rain \nand seep into the nearby soil, improper waste management techniques, \nwhich are characterized by release of sewage into the large dumping \ngrounds and nearby streams or rivers.<br>\nLight pollution is described as excessive and incorrect artificial light\n (Mizon, 2002). It is caused due to extreme use of artificial lights by \nhumans. The powerful artificial light which are used to brightens \noffices, factories, sports stadium, street, parks and sometime even \nhousing complexes obscure the night sky.\n<\/p>\n\n\n\n<p>\n The four components of light pollution are often combined and may intersect:<br>\n <\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Urban Sky Glow: The brightening of the night sky over inhabited areas.<\/li>\n\n\n\n<li>Light Trespass: Light falling where it is not intended, wanted, or needed.<\/li>\n\n\n\n<li>Glare: Excessive brightness which causes visual discomfort. High levels of glare can decrease visibility.<\/li>\n\n\n\n<li>Clutter: Bright, confusing, and excessive groupings of light <br>sources, commonly found in over-lit urban areas. The proliferation of <br>clutter contributes to urban sky glow, trespass, and glare.<\/li>\n<\/ol>\n\n\n\n<p>\nPlethora of environmental studies have shown that environmental \npollutants have various adversarial health effects. The most important \nharmful effects are prenatal disorders, infant mortality, respiratory \ndisorders, allergy, malignancies, cardiovascular disorders, and increase\n in stress oxidative, endothelial dysfunction, mental disorders, and \nvarious other harmful effects. Though, short-term effects of \nenvironmental pollutants are usually underlined, wide range of hazards \nof air pollution from early life and their possible implication on \nchronic non-communicable diseases of adulthood should be underscored. \nMany studies have demonstrated that environmental particulate exposure \nhas been linked to increased risk of morbidity and mortality from many \ndiseases, organ disturbances, cancers, and other chronic diseases \n(Kargarfard, 2011). Consequently, experts advised to take immediate \naction and control the pollution. Otherwise, the waste products from \nconsumption, heating, agriculture, mining, manufacturing, \ntransportation, and other human activities will damage the environment.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-environmental-degradation\">Environmental Degradation<\/h2>\n\n\n\n<p>\n  Environmental degradation is a consequence of the active inter play of\n socio-economic, institutional and technological actions. Environmental \ndegradation is a process through which the natural environment is \ncompromised in some way, decreasing biological diversity and health of \nthe environment. Environmental degradation is described as the worsening\n of physical components of the environment brought in by human \nactivities to such an extent that it cannot be set right by \nself-regulatory mechanism of environment. This process can be completely\n natural in origin, or it can be fast-tracked or caused by human \nactivities. Many global organizations identify environmental degradation\n as major threats to communities, planets. Environmental changes may be \ndriven by numerous factors such as economic development, population \ngrowth, and urbanization, intensification of agriculture, more energy \nuse and transportation. Poverty is also major issue which creates \nenvironmental problems. The economics of environmental pollution, \ndepletion and degradation of resources has been ignored as compared to \nthe issues of growth and expansion. India is also facing problems of \nenvironmental degradation because of the considerable increase in its \npopulation.\n\n\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-factors-that-led-environmental-degradation\">Factors that Led Environmental Degradation<\/h2>\n\n\n\n<p>\nThere are basically two factors namely:<br>\n1. Natural factors such as drought, storms on sea, land and deserts such\n as hurricanes, tornadoes, carina and volcanic eruptions. These factors \nlead to land degradation through erosion.<br>\n2. Human factors which include deforestation, industrialization and \nurbanization. These factors lead to water, air and land pollution.\n\n\n\n\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-types-of-environmental-degradation\">Types of Environmental Degradation <\/h2>\n\n\n\n<p>\nTypes of environmental degradation:<br><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Types-of-environmental-degradation.png\" alt=\"Environmental Degradation\" title=\"\"><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-deforestation\">Deforestation<\/h2>\n\n\n\n<p> Deforestation is the \nprocess of clearance of forests by logging and\/or burning. Deforestation\n occurs due to many reasons that include trees or derived charcoal are \nused as, or sold, for fuel or as a commodity, while cleared land is used\n as grassland for livestock, plantations of commodities, and \nsettlements. The exclusion of trees without sufficient reforestation has\n resulted in harm to habitat, biodiversity loss and dryness. It has \nadversative impacts on bio-sequestration of atmospheric carbon dioxide. \nDeforested regions characteristically sustain substantial adverse soil \nerosion and frequently damage into wasteland. \n\n\n<\/p>\n\n\n\n<p><strong>Causes of deforestation:<\/strong> There are several causes of current \ndeforestation such as dishonesty of government institutions, the unfair \ndistribution of wealth and power, population growth and overpopulation, \nand urbanization. Globalization is also major cause of deforestation, \nthough there are cases in which the impacts of globalization have \nsupported localized forest recuperate. <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Causes-of-deforestation.png\" alt=\"Deforestation\" title=\"\"><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-extinction\">Extinction<\/h2>\n\n\n\n<p> It is the process by which a \nspecies, genus, or family, becomes extinct no longer existing and living\n in the world. It is the elimination and annihilation of something that \npreviously existed in the world. In the arena of biology, it denotes \nspecifically to the end of an evolutionary line, or a branch on the tree\n of life. The extinction of a species can have significant consequences \nfor an ecosystem and even for the physical environment and climate, \noften leading to further extinctions.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-desertification\">Desertification:<\/h2>\n\n\n\n<p> Desertification is the\n ruin of land in waterless and dry sub-humid areas due to many factors \nsuch as climatic changes and human activities. Desertification results \nprimarily from man-made activities. It is mainly caused by overgrazing, \nover drafting of groundwater and diversion of water from rivers for \nhuman consumption and industrial use, all of these processes are \nfundamentally driven by overpopulation. Main effect of desertification \nis reduced biodiversity and weakened productive capacity, for example, \nby transition from land dominated by shrub lands to non-native \ngrasslands.\n\n<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Causes-of-deforestation.png\" alt=\"Desertification\" title=\"\"><\/figure>\n\n\n\n<p>\n\t<strong>Causes of desertification:<\/strong> Desertification occurs due to \nnumerous factors, primarily anthropogenic causes, which began in the \nHolocene era and continues today. The primary reasons for \ndesertification are overgrazing, over-cultivation, increased fire \nfrequency, water impoundment, deforestation, over drafting of \ngroundwater, increased soil salinity, and global climate change.<br>\nMultilevel set of causes of Desertification (Source: Camilla Toulmin, 1993)<br>\n\n\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-emmision\">Emmision<\/h2>\n\n\n\n<p>  Emission is process in which \nhuman or natural forces discharge chemicals or other substances into the\n environment. Emission leads to pollution such as emission is caused \nwhen chemicals are released into the air. Many natural processes cause \nemissions. When a volcano explodes, it lets out acid, and acid, ash, and\n many toxic gases. When fires break out in forests, they release smoke, \nsoot, carcinogenic hydrocarbons, dioxins, and carbon dioxide.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-erosion\">Erosion<\/h2>\n\n\n\n<p> Erosion is the procedure of weathering \nand carriage of solids in the natural environment or their source and \ndeposits them elsewhere. It generally occurs due to transport by wind, \nwater, or ice, by down-slope creep of soil and other material under the \nforce of gravity; or by living organisms, such as burrowing animals, in \nthe case of bio-erosion.<br>\nA certain amount of erosion is natural and, it is good for the \necosystem. Erosion is different from weathering, which is the process of\n chemical or physical breakdown of the minerals in the rocks, although \nthe two processes may occur simultaneously.<br><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-causes-of-environmental-degradation\">Causes of environmental degradation<\/h2>\n\n\n\n<p>\n Due to increased activities of humans and release of harmful chemicals,\n environmental conditions deteriorated and impact on human health. There\n are many causes of environmental degradation. The speedy population \ngrowth and economic development in country are degrading the environment\n through the unrestrained growth of urbanization and industrialization, \nexpansion and intensification of agriculture, and the obliteration of \nnatural surroundings. Main reason of environmental degradation in India \nis unparalleled growth of population, which is unfavourably affecting \nthe natural resources and environment. The increasing population and the\n environmental deterioration face the challenge of continued development\n without environmental damage. Population impacts on the environment is \nmainly through the use of natural resources and production of wastes and\n is related with environmental stresses like loss of biodiversity, air \nand water pollution and increased pressure on arable land.<br>\n\nAnother major cause of environmental degradation pointed out by \nenvironmentalists is Poverty. The circular link between poverty and \nenvironment is a tremendously complex phenomenon. Inequality may raise \nunsustainability because the poor, who rely on natural resources more \nthan the rich, deplete natural resources faster as they have no real \nprospects of gaining access to other types of resources. Moreover, \ndegraded environment can quicken the process of destitution, again \nbecause the poor depend directly on natural assets.<br>\n\nIt has been observed that poor people migrate to urban areas due to lack\n of opportunities for profitable employment in villages and the \necological stresses. Extra-large cities are emerging and urban slums are\n expanding. Such rapid and unplanned development of cities has resulted \nin ruin of urban environment. It has broadened the gap between demand \nand supply of infrastructural services such as energy, housing, \ntransport, communication, education, water supply and sewerage and \nrecreational amenities, thus depleting the valuable environmental \nresource base of the cities. The result is the growing trend in \nworsening of air and water quality, generation of wastes, the \nproliferation of slums and undesirable land use changes, all of which \ncontribute to urban poverty.<br>\n\nThere are some economic factors that lead to environmental degradation. \nEnvironmental degradation is the consequence of market failure, that is,\n the non-existent or poorly functioning markets for environmental goods \nand services. In this framework, environmental degradation is a \nparticular case of consumption or production externalities reflected by \ndivergence between private and social costs (or benefits). Market \nmisrepresentations created by price controls and subsidies may \nexacerbate the achievement of environmental objectives.<br>\n\nTransport activities intensely effects on the environment such as air \npollution, noise from road traffic and oil spills from marine shipping. \nTransport infrastructure in India has expanded significantly in terms of\n network and services. Thus, road transport accounts for a major share \nof air pollution load in cities such as Delhi. Port and harbour projects\n mainly impact on sensitive coastal eco systems. Their construction \naffects hydrology, surface water quality, fisheries, coral reefs and \nmangroves to varying degrees.<br>\nEffect of agricultural development on the environment ascend from \nfarming activities which contribute to soil erosion, land salination and\n loss of nutrients. \n\n\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-effects-of-environmental-degradation\">Effects of Environmental Degradation<\/h2>\n\n\n\n<p>\n1. Impact on Human Health: Human health is greatly impacted by the \nenvironmental degradation. Areas exposed to toxic air pollutants can \ncause respiratory problems like pneumonia and asthma. Most of people \nloss their life due to indirect effects of air pollution.<br>\n2. Loss of Biodiversity: Biodiversity is vital to sustain balance of the\n ecosystem in the form of combating pollution, restoring nutrients, \nprotecting water sources and stabilizing climate. Deforestation, global \nwarming, overpopulation and pollution are few of the major causes for \nloss of biodiversity.<br>\n3. Ozone Layer Depletion: Ozone layer is responsible to shield earth \nfrom detrimental ultraviolet rays. The presence of chlorofluorocarbons, \nhydro chlorofluorocarbons in the atmosphere is causing the ozone layer \nto deplete. As it will deplete, it will emit harmful radiations back to \nthe earth.<br>\n4. Loss for Tourism Industry: Speedy activities of tourism industry is \nalso responsible for the worsening of environment that rely on tourists \nfor their daily livelihood. Environmental damage in the form of loss of \ngreen cover, loss of biodiversity, huge landfills, increased air and \nwater pollution can be a big turn off for most of the travellers.<br>\n5. Economic Impact: The huge cost that a nation may have to borne due to\n environmental degradation can have huge economic impact in terms of \nrestoration of green cover, cleaning up of landfills and protection of \nendangered species. The economic impact can also be in terms of loss of \ntourism industry.<br>\nThe potentials of human economic activity leading to regional and \nworld-wide conflicts especially as the emission of dangerous gases into \nthe atmosphere (environmental degradation) results in changes in \nagriculture production and inaccessibility of resources eventually \ncausing food scarcities.\n\n\n<\/p>\n\n\n\n<p><strong>Impact of environmental degradation (Source: Chalecki, 2003)<\/strong><br><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.civilserviceindia.com\/subject\/General-Studies\/notes\/images\/Impact-of-environmental-degradation.png\" alt=\"Environmental Degradation\" title=\"\"><\/figure>\n\n\n\n<p> To summarize, Pollution is due to harmful substances or products into  the environment. There are several types of pollutions in the  environment such as Water Pollution, Air Pollution, Soil Pollution, land  pollution. Environmental degradation is the collapse of the earth or  worsening of the environment through consumption of assets such as air,  water and soil, the destruction of environments and the annihilation of  wildlife. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-essay-with-ai-enhanced-writing-skills-by-using-chatgpt-as-below\">Essay with AI Enhanced writing skills by using CHATGPT as below- <\/h2>\n\n\n\n<p>Environmental pollution and degradation are two of the most pressing issues facing our planet today.
