Environmental issues Essay

It was non yet cognize by the universe the seriousness of the purlieual problems we heart if not for the issue on global warming. lashings of organizations, umpteen of them with inter demesneal memberships, argon now works on everything from saving wildlife to developing new sources of energy. scarcely pollution, energy consumption and stinting addition atomic number 18 independent problems. Effective programs for dealing with 1 of them a great deal aggravate the others. For example, devices that clean automobile exhaust and reduce look pollution also decreases go off economy, t hereby using up our limited reserves much rapidly. Similarly, banning the keen of ho intentionhold trash reduces pushover pollution but increases environmental pollution, as land, animals and scenery are sacrificed for strip taps and oil wells, and the wastes produced by the fuel are dumped into the environment. On the other hand, ignoring the need for more energy retards the economy, the reby increasing unemployment and possibly simplification food production.Nature is fighting back against the abuses we incur inflicted upon it Due to human carelessness that damaged the environment, many communities are now suffering from environmental crises. The transfer that you breathe contains gases much(prenominal) as oxygen, nitrogen and carbon dioxide in certain amounts. But many quite a little live in areas where the line of work contains pollutants that are denigratory to their health. spread pollution is a common problem in congested and urban areas (The Washington generation 2006, p.26). Food, air and water tot up needed for lifes processes which the environment provides unfortunately contain detrimental substances called pollutants. The heraldic bearing of air, water and soil in the environment is of waste materials or pollutants which the environment cannot handle, degrade, disperse or propagate so that it turn overs unclean and unhealthy is called pollu tion (Colla 2002, p.125). thither are four general types of pollution, namely1. bloodline Pollution It is an undesirable change in the physical and chemical characteristics of air. Industrial plants, motor vehicles, indiscriminate throwing and burning of refuse everywhere book the air polluted. Cigarette smoking contributes to air pollution, most especially in enclosed places. Foul smell from waste and methane gas emitted through the combustion of refuse contributes to the problem of air pollution (Kemp1994, p.23).Prolonged exposure to air pollution whitethorn cause/aggravate respiratory and other diseases as well as irritation of the eyes, nose and throat.2. Water Pollution this results when water contains more harmful substances such as harmful bacteria and poisonous chemicals, than it can lifelikely get rid of. The toss of domestic and industrial wastes into the rivers, canals, and other water bodies causes pollutants to be introduced into waterways. Frequent flooding whic h carry topsoil and sewage into the water supplies pollute the water, too. Sugar mills, distillers and mining firms with forbidden proper waste disposal systems are among the principal polluters of the nations waterways. Soap and water detergents produce enormous persistent layers of suds on the surface of withdraw waters.Substances such as harmful bacteria and poisonous chemicals are likely to cause gastro-intestinal diseases, cholera, typhoid fever, dysentery, septic hepatitis, food poisoning and level death.Mercury in sea water is absorbed by piffling plants that provide food for small fish, which is eaten by a larger fish. When they are eaten by men, mercury is deposited in the kidneys and brain which may cause death when accumulated (Kemp 1994, p.23).3. Land Pollution This takes place when harmful substances are introduced into the soil making it unable to sustain plant life. Dumping areas are breeding places of disease carriers such as flies, rodents, mosquitoes and cock roaches.Uses of excessive amounts of fertilizer, pesticides and other toxic chemicals can destroy the ability of the soil to self-generate. They deplete the nutrients, ponderousen the texture, and increase toxicity, making the soil less productive.Other causes of land pollution are atomic fallouts and mine tailings which poison agricultural lands. Toxic residues from the accumulation of chemicals in the land can cause cancer and other diseases (Kemp 1994, p.24).4. Noise Pollution (Persistent noise) This refers to the presence of too loud, too sudden or very unpleasant vowelize that becomes an assault to the body causing mental or physical harm. The roaring of motor vehicles, grating secure of jackhammer, squeaking of tires, screeching brakes, blaring television sets, radios and stereos and even loud shouting are some types of touch-and-go noises when one is continuously exposed to them. Noise pollution affects not only the ears but also promptly or indirectly impairs the mind and the whole body. Directly, it can cause deafness indirectly, it may lead to increase heart beat and high blood pressure that eventually cause cardiovascular disease (Kemp 1994, p.24). or so pollution is caused by man, pollutants go forth increase as population grows, and hence, minimizing the production of pollutants and managing its proper disposal mustiness be the goal of every human being.But the air pollution must be tending(p) extra attention by the government, society and each individual to protect people from this environmental danger, not only for ourselves but for future generations. disseminate Pollution, Environmental Hazard in that respect are five elementary pollutants of air are carbon monoxide, treat oxide, hydrocarbons (organic compounds made up of hydrogen and carbon) and small divorceicles that float in the air (Jordan 2005, p.12-20).Sources of Air Pollution1. Automobile exhaustsThe poisonous carbon monoxide in the air comes from automobiles. Nitrogen oxi de and hydrocarbons are also produced as by-products of engine combustion. The more vehicles there are on the road, the greater is the possibility of pollution. lead-free gasoline and some anti-pollution automobile parts cut down the amount of pollutants in the air. But expatriation vehicles are still a major cause of air pollution.2. IndustryIndustries are responsible for the fleck largest amount of pollution in the air, next only to vehicles. Fuels that are used in some industries may give off large amounts of sulfur oxide, nitrogen oxide and harmful particles of dust and ash. Sulfur oxide is made when fuels containing sulfur like coal are burned. Certain industrial processes may give off more of one pollutant than another. This depends on the kind of fuel used and the product that is being made.3. IndividualsPeople pollute the air in many ways. Each epoch a person smokes a cigar/cigarette, the air is being polluted when he burns trash, air pollution is increased. More polluti on is added when he uses wood for cooking or to extend warm during the cold months or cool during the hot months.Effects of Air Pollution1. Respiratory disordersIf you have breathed polluted air, the eyes may water, the nose may run and a cough may develop. Serious illnesses are likely to happen to people long exposed to polluted air. Chronic bronchitis, pulmonary emphysema and lung cancer are common in air polluted areas. Cigarette smoking is closely associate to the development of long cancer. Heart diseases, especially heart attacks occur more in places where there is a high level of carbon monoxide in the air.1. AccidentsVehicle accidents happen more often in places where air is polluted. These accidents may be caused by poor visibility in the polluted air. Or they may be caused by increased exposure to carbon monoxide. People with watery eyes, headaches and breathing problems often find it hard to drive in air polluted areas.2. High economic costThe government may reach bill ions of pesos per social class to control air pollution. However, little has been done by the government to control air pollution due to the struggling economy and the low economic growth. The United States spends around 4o billion dollars a year to control air pollution. The cost of air pollution is about 200 dollars per year for each person.Air pollution can also add to the rusting and corrosion of vehicles and machinery. Even farm crops may be harmed or stunted in growth by air pollution.There is a way out of this trap. In a word, it is sacrifice. The fact that there is no way both to clean up the environment and conserve subjective resources without changing the life-style of people in the industrialized nations. The take exception is that of motivating people to make the necessary changes now, before a worldwide disaster forces much more difficult adjustments upon us.Preventing of Air PollutionEveryone needs to care more about the problem of air pollution. Car exhausts and a ir teach systems can be checked at regular times and kept in good working condition. Air conditioners, if not working properly, may give off harmful hydrocarbons. Vehicles should not be allowed to hazardous for more than a few minutes because idling lets carbon monoxide escape in the sir. Use of public transportation would also tear down the number of vehicles on the road and in return would also lower air pollution. Strict laws on transportation and industry must be enforced.Instead of burning trash, it should be allowed to decompose in pits. The decomposed materials can be utilized as fertilizer for plants and at the same time minimizes smoke in the air. Stricter laws on cigarette smoking should also be enforced. The end result of this is lesser lung and heart ailments and cleaner atmosphere (Cline 1992, p.35-37).Political ActionThe real problem comes from the wealth the power of the opponents of environmental protection. On the local level, environmentalist face rich land deve lopers who can make large ply contributions to the politicians who decide what land may or may not be developed. At higher levels of government, environmentalists face even more powerful foes multinational corporations that stand to make big profits from despoiling the environment. Included here are some of the most powerful corporations in the world, such as petroleum and mineral companies that loss to sink wells and mines in fragile wilderness areas, the manufacturers that spew pollutants into the air and water, and the firms that sell products such as polluting automobiles and unsafe pesticides. Such corporations have spent hundreds of million dollars to persuade the government not to outlaw their bad activities (Diehl, p.20-21). The environmentalists and the concerned public simply do not have that kind of money.If we are to preserve the natural environment for ourselves and the generations to come, two things must be done. First, a stronger educational campaign must be launc hed to make more people aware of environmental problems. Second, more ordinary citizens must join together and become involved in the political action necessary to strengthen anti-pollution laws, increase the enforcement effort, and protect our natural resources.Conserving ResourcesThere is no doubt that our existing resources can be used far more efficiently. It is possible for a large-scale, multiple-stage recycling program to be introduced in imitation of natural ecosystems. To take a simple example, drool could be used as fuel to run the mills to make recycled paper, the wastes from which could be burned as fuel. Similarly, it is possible that community water districts will some day become closed systems, humbleing that the water would be used again and again, never being discharged into an ocean or river. Some factories already have such closed systems (Sarewitz 2000, p.55). It is possible to envision larger closed systems designed so that no industrial material would ever be discarded as either waste or pollution. muscularity conservation can also stretch our natural resources. Insulating homes, driving smaller cars at slower speeds, equitation trains and buses instead of driving cars, recycling the heat used in factories, and restricting the manufacture of energy-wasting gadgets are provable ways of eliminating waste. The immediate task is not to develop technologies that are more energy sufficient the challenge is to find ways or persuading people to use the conservation measures that are already available.Better engineeringA growing number of scientists and concerned citizens are coming to see solar system as the best answer to the worlds energy problems. Solar power units use the endless supply of energy from the sun, are nonpolluting, and pose no threat of radiation or explosion. Other promising approaches use specially prepared ponds of water to trap solar energy or mirrors to concentrate it on a single location, where it can be used to generate electrical power (Tennesen 2004, p.85).Limiting Growth proficient solutions are attractive, but it is doubtful that they alone can resolve the environmental crisis. It is often argued that industrial growth is necessary to create new jobs for a growing population. The argument that economic growth is necessary to kill poverty and create a more egalitarian society is also misleading. Despite decades of rapid economic growth, the industrialized nations continue to show enormous inequalities of wealth and power (1991, p.12).ConclusionThe environmental crisis does not mean everyone should return to hunting and gathering the worlds current population is too large to even consider such an idea. Keeping a clean environment is the responsibility of the government, society and each individual. Today, air pollution must be given extra attention to protect people from this environmental danger. in all of us must have aknowledge of this environmental menace. The young generations today, like us, crave for the total preservation of our natural resources, earnestly begging to put an end to wastage and preserve the natural wealth intended by our stimulate Earth for the future.Yes, there is still gleaming hope to save our Mother Earth from total destruction. There is still a chance to regain the lost paradise we unscrupulously abused. We must do our part to make this world a safer place to live in, not just for ourselves and our neighbors but our future generations. The will to dynamic implementation to this urgent call lies in your strong and sustainable support, giving once more Mother Earth a chance to care for our lives now and in the future generations.
