Environmental issues Essay

It was non yet realized by the public the seriousness of the environsal problems we mettle if non for the issue on global warming. Dozens of organizations, many of them with external memberships, argon in a flash working on boththing from saving wildlife to developing current sources of button. But pollution, energy consumption and economic growth be supreme problems. Effective programs for dealing with atomic number 53 of them a lot aggravate the new(prenominal)s. For example, devices that clean simple machine exhaust and reduce expression pollution also decreases fuel economy, t here(predicate)by using up our limited reserves more fastly. Similarly, banning the eager of ho uptakehold trash reduces disperse pollution and increases environmental pollution, as consume, animals and scenery argon sacrificed for strip mines 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 retard s the economy, thereby change magnitude unemployment and possibly reducing food harvest-tideion.Nature is fighting back against the ab engages we hasten inflicted upon it Due to human carelessness that damaged the environment, many communities are now suffering from environmental crises. The air that you breathe contains gases such as oxygen, nitrogen and degree Celsius dioxide in certain amounts. But many people peppy in areas where the air contains pollutants that are harmful to their health. spread pollution is a common problem in congested and urban areas (The Washington time 2006, p.26). Food, air and water needed for lifes processes which the environment provides unluckily contain harmful substances called pollutants. The nominal head of air, water and vulgarism in the environment is of waste materials or pollutants which the environment apprise non handle, degrade, disperse or diffuse so that it becomes unclean and unhealthy is called pollution (Colla 2002, p.125 ). at that place are four familiar types of pollution, namely1. Air taint It is an undesirable change in the physiologic and chemical characteristics of air. Industrial plants, motor vehicles, indiscriminate throwing and burning of refuse all over make the air contaminated. Cigarette hummer contributes to air pollution, most in particular in enclosed places. Foul smell from waste and methane gas emitted with the combustion of refuse contributes to the problem of air pollution (Kemp1994, p.23).Prolonged pic to air pollution whitethorn cause/aggravate respiratory and other ailments as well as irritation of the eyes, nose and throat.2. Water defilement this results when water contains more harmful substances such as harmful bacterium and pestiferous chemicals, than it arse naturally get rid of. The dumping of home(prenominal) and industrial wastes into the rivers, gutterals, and other water bodies causes pollutants to be introduced into water slipway. Frequent flooding which study topsoil and sewage into the water supplies pollute the water, too. Sugar mills, distillers and mining firms without seemly waste disposal agreements are among the principal polluters of the nations waterways. lash and water detergents produce enormous persistent layers of suds on the bob up of receding waters.Substances such as harmful bacteria and poisonous chemicals are equally to cause gastro-intestinal diseases, cholera, typhoid f of all time, dysentery, infectious hepatitis, food poisoning and train terminal.Mercury in sea water is absorbed by minute plants that provide food for small-scale fish, which is eaten by a over big 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 teaching places of disease carriers such as flies , rodents, mosquitoes and cockroaches.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, hard-foughten 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 resi ascribables from the accumulation of chemicals in the land can cause genus 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 croak that becomes an assault to the body causing mental or physical harm. The microphone boom of motor vehicles, grating sound of jackhammer, squeaking of tires, screeching brakes, blaring boob tube sets, radios and stereos and eve loud shouting are several(prenominal) types of dangerous noises when one is continuously ex framed to them. Noise pollution affects no t only the ears but also directly or indirectly impairs the mind and the whole body. Directly, it can cause deafness indirectly, it may lead to increased bone marrow break exhaust and high blood pressure that eventually cause cardiovascular disease (Kemp 1994, p.24).Most pollution is ca employ by man, pollutants bequeath increase as existence grows, and hence, minimizing the production of pollutants and managing its proper disposal must be the goal of every human being.But the air pollution must be inclined extra attention by the government, society and each individual to foster people from this environmental danger, not only for ourselves but for future generations.Air Pollution, Environmental HazardThere are five basic pollutants of air are carbon monoxide, sec oxide, hydrocarbons (organic compounds made up of hydrogen and carbon) and small particles 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 oxide and hydrocarbons are also produced as by-products of engine combustion. The more vehicles there are on the road, the greater is the conjecture of pollution. Unleaded gasoline and some anti-pollution automobile parts cut down the amount of pollutants in the air. But transportation vehicles are still a major cause of air pollution.2. IndustryIndustries are responsible for the secondly largest amount of pollution in the air, next only to vehicles. Fuels that are employ in some industries may give out 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 dep shuttings on the kind of fuel utilize and the product that is being made.3. IndividualsPeople pollute the air in many ways. individually time a person scum bags a cigar/cigarette, the air is being polluted when he burns trash, air pollution is increased. More pollution is added when he uses wood for cooking or to keep warm during the cold months or cool during the hot months.Effects of Air Pollution1. Respiratory disordersIf you pay off breathed polluted air, the eyes may water, the nose may rifle and a cough may develop. Serious illnesses are likely to relegate to people long exposed to polluted air. Chronic bronchitis, emphysema and lung cancer are common in air polluted areas. Cigarette smoking is closely related 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 video to carbon monoxide. People with watery eyes, headaches and breathing problems often find it hard to drive in air pol luted areas.2. High economic bellThe government may spend megs of pesos per year to control air pollution. However, half-size 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 far-offm 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 item that there is no way both to clean up the environment and conserve natural resources without changing the life-style of people in the industrialize nations. The challenge 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 abo ut the problem of air pollution. motorcar exhausts and air conditioning systems can be checked at firm times and kept in good working condition. Air conditioners, if not working properly, may give off harmful hydrocarbons. Vehicles should not be allowed to idle for more than a few minutes because idling lets carbon monoxide escape in the sir. Use of public transportation would also disgrace 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 fillThe real problem comes from the wealth the tycoon of the opponents of environmental protection. O n the local level, environmentalist face rich land developers who can make large campaign contributions to the politicians who decide what land may or may not be developed. At higher levels of government, environmentalists face even more omnipotent 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 want to sink wells and mines in sparse wilderness areas, the manufacturers that spew pollutants into the air and water, and the firms that sell products such as polluting automobiles and grievous pesticides. Such corporations have spent hundreds of million dollars to persuade the government not to outlaw their destructive activities (Diehl, p.20-21). The environmentalists and the concerned public simply do not have that kind of money.If we are to celebrate the natural environment for ourselves and the generations to come, ca rdinal things must be done. First, a stronger educational campaign must be launched to make more people aware of environmental problems. Second, more middling citizens must join together and become involved in the semipolitical 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, garbage 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, meaning that the water would be used again and again, never being discharged into an ocean or river. somewhat factories already have such closed systems (Sarewitz 2000, p.55). It is possibl e to envision larger closed systems designed so that no industrial material would ever be discarded as either waste or pollution. efficiency conservation can also stretch our natural resources. Insulating homes, driving little cars at slower speeds, riding trains and buses instead of driving cars, recycling the set off used in factories, and restricting the manufacture of energy-wasting gadgets are obvious 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 TechnologyA emergence 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 en ergy or mirrors to concentrate it on a single location, where it can be used to generate electrical power (Tennesen 2004, p.85).Limiting GrowthTechnological 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 bring out new jobs for a festering population. The argument that economic growth is necessary to eliminate 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 concourse the worlds current population is too large to even consider such an idea. Keeping a clean environment is the righteousness of the government, society and each individual. Today, air pollution must be disposed extra attention to protect people from this environmental danger. All of us must have aknowledge of this environmental menace. The young generations today, like us, crave for the jibe preservation of our natural resources, earnestly begging to put an end to wastage and preserve the natural wealth intended by our Mother Earth for the future.Yes, there is still gleaming hope to save our Mother Earth from descend destruction. There is still a materialise to regain the lost heaven 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.
