Today,we are gathering here to discuss a very hot issue. how to find harmony in a new age between man and nature? Where modern science and technology are concerned I am only a layman I have to say. However, living in this "new age" , seeing my dear ones suffering from respiratory diseases from time to time, finding the beautiful colors of green and blue are being replaced by that of gray and pale, and realizing that our mother planet is getting more and more unhealthy; I cant help trying to offer my idea and my trivial efforts to look for the answer of the question.As the ancient Greek oracle goes: know thyself. I think in answering this above-mentioned question, this precondition is also very important.Who are we? This is a question, which should be answered not only by those specialists, but also by every one of human beings.Some people may proudly say: we are the masters of nature. It is true that the idea of "man can conquer nature" has dominated peoples mind for years, and it is true, man has kept acting like a master and doing whatever things he wants for thousands of years. However, as the consequence of this kind of "leadership" , now the "master" seems to be confronted with problems that are far beyond his control. Facts are really very ample. Thegreen house effect leaves islands and cities along the coast, such as this oriental pearl-Shanghai, in danger of the disaster of being drowned; the holes of the ozone layer make the earth less suitable to live for some creatures including human beings; the phenomena of EL Nino and La Nina leave the land with seriousflood and drought, and the diseases, caused by pollution, are increasing at an incredible speed... Seeing all these facts, can we still ignore the counterattack of nature? We are not the masters of nature. Facing all the disasters made by ourselves, we, mankind as a whole should realize that we are just a normal member of the big family of nature. Any mistreatment towards nature will meet only with the revenge from her.By saying so, I do not mean we should give a sudden stop to any development. Because that will result in a threat to the existence of human society. I mean we should treat nature equally, leaving the chance of existence and development to nature as we are obtaining the same thing, and thus we will get the situation of win-win.I am very pleased to find that now more and more people, from every corner of the planet, have come to realize that harmony with nature is the only way to universal and continuous progress and prosperity. And I think that is why we come here from all over the country to discuss this topic today.I want to end my speech by quoting from Mr. Nixon. "Our destiny offers, not the cup of despair, but the chalice of opportunity." The future is not ours to see of course. However, by seizing firmly the opportunities, by knowing clearly about ourselves, we, human beings, can doubtlessly achieve the real harmony with nature!Thank you.以保护环境为主题的英文演讲稿4We live in the world every day.We eat food, drink water, wear clothes, watch TV, use computers and so on.We are producing waste every moment.Generally speaking, there are four sorts of waste.They are material waste, organic waste, inorganic waste and poisonous & harmful waste.Now, we are going to talk about each sort of waste one by one.Material waste: it means the waste of substance or things from which something else can be made.For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates.At last, they become waste.For example, when people finish reading newspaper, the paper will become waste.When the glass is broken, it also becomes waste.Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses.Once it is broken, it becomes waste.The rate of using plastics is increasing day by day.People use plastic bags because they are convenient.When they get home, they throw the plastics way, paying no attention to the environment.The more convenience plastics brings to us, the more plastic waste is produced.This is called “white pollution” as most plastics are white.Some of our products we use every day are made of rubber, just like the tyres and the bottom part of our shoes.It’s true that rubber plays an important role in our life.However, it also brings us some trouble when it has been used for a long time and becomes old.The old tyres become waste because it can’t break down by nature.This is really a big problem.以保护环境为主题的英文演讲稿5Hello:everyone!Now I want to talk about a beatiful world!When I was young,I always dreamed that I lived in a beautiful country.There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing.The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment.Everyone should make a contribution to protect the environment.Taking care of our environment is very important.Wherever you live,you can do something around your neighbourhood.Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls?Have you ever spat in a public place?Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment.It is our duty to keep our envionment clean and tidy.You might ask yourself,"Have I ever picked up some rubbish and thrown it into a dustbin?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment.Now I want to say :Lets do our best to make our world more beautiful!。
Good morning/afternoon/evening. It is my great honor to stand before you today to address a topic that is of paramount importance to the future of our planet: environmental protection. The state of our environment is a reflection of our collective actions, and it is time for each one of us to take a stand and commit to a sustainable and eco-friendly lifestyle.As we all know, the Earth is our only home, and it is under severethreat from human activities. Climate change, pollution, deforestation, and the loss of biodiversity are just a few of the critical issues that we are facing. If we do not take immediate and decisive action, these problems will only worsen, and the consequences will be dire for both present and future generations.Let us begin by acknowledging the severity of the situation. The Intergovernmental Panel on Climate Change (IPCC) has reported that the global temperature has risen by 1.1 degrees Celsius since pre-industrial times, primarily due to the increase in greenhouse gas emissions. This rise in temperature has led to more frequent and severe weather events, rising sea levels, and the loss of polar ice caps. The loss of biodiversity is equally alarming, with species extinction rates at anall-time high due to habitat destruction, pollution, and climate change.So, what can we do to address these challenges? The answer lies in our hands, and it starts with individual responsibility. Here are some key steps that we can take to promote environmental protection:1. Reduce, Reuse, Recycle: This is a mantra that we must all embrace. By reducing our consumption of single-use plastics, paper, and other non-biodegradable materials, we can significantly reduce waste. Reusing items whenever possible and recycling what we cannot avoid can also make a substantial difference.2. Conserve Energy: Energy conservation is crucial in reducing greenhouse gas emissions. We can turn off lights when not in use, unplug devices, and switch to energy-efficient appliances. Additionally, adopting renewable energy sources such as solar and wind power can greatly reduce our carbon footprint.3. Sustainable Transportation: Transportation is a major contributor to air pollution and greenhouse gas emissions. By choosing public transportation, carpooling, biking, or walking, we can reduce our carbon emissions and promote a cleaner environment.4. Support Sustainable Agriculture: The food we eat has a significant impact on the environment. By supporting organic farming, reducing food waste, and choosing locally sourced products, we can promote sustainable agricultural practices that are less harmful to the planet.5. Protect Natural Resources: Conserving water, protecting forests, and preserving wetlands are essential for maintaining ecological balance. We must ensure that our actions do not harm these vital ecosystems.6. Educate and Raise Awareness: Knowledge is power. By educating ourselves and others about environmental issues, we can foster a culture of sustainability and inspire positive change.7. Advocate for Policy Change: It is important to support policies that promote environmental protection at both the local and global levels. This includes advocating for stricter regulations on pollution, the promotion of renewable energy, and the conservation of natural resources.8. Lead by Example: As leaders, influencers, and change-makers, it is our responsibility to lead by example. By making eco-friendly choices in our personal and professional lives, we can encourage others to do the same.In conclusion, environmental protection is not a luxury but a necessity. It is the only way to ensure that our planet remains habitable forfuture generations. We must act now, and we must act together.As individuals, we can start by making small changes in our daily lives. By reducing our consumption, conserving resources, and supporting sustainable practices, we can contribute to a healthier and more sustainable world. As communities, we can organize clean-up drives, promote green initiatives, and educate our neighbors about the importance of environmental protection. As nations, we can work togetherto develop and implement global agreements that address climate change and environmental degradation.Ladies and gentlemen, the time for action is now. It is up to us to protect our planet, to ensure that it remains a vibrant and beautiful place for all living beings. Let us not delay, let us not wait for others to take the lead. Let us be the change that we wish to see in the world.Thank you for your attention, and let us embark on this journey of environmental protection together.[Your Name]。
environment的英文作文Title: The Importance of Environmental Conservation。
In today's world, the environment plays a crucial role in sustaining life on Earth. The term "environment" encompasses everything around us, including the air we breathe, the water we drink, the land we inhabit, and the diverse range of plant and animal species that coexist with us. Therefore, it is imperative that we prioritize environmental conservation efforts to ensure the well-being of current and future generations.One of the primary reasons why environmental conservation is essential is to preserve biodiversity. Biodiversity refers to the variety of life forms present on Earth, including plants, animals, and microorganisms. Each species plays a unique role in maintaining ecological balance and contributing to ecosystem services such as pollination, nutrient cycling, and climate regulation. However, human activities such as deforestation, habitatdestruction, pollution, and overexploitation have led to a significant loss of biodiversity worldwide. By conserving natural habitats and protecting endangered species, we can help safeguard the intricate web of life that sustains us.Furthermore, environmental conservation is crucial for ensuring the availability of essential resources such as clean air and water. Air pollution, primarily caused by emissions from vehicles, industries, and agricultural practices, poses a significant threat to human health and the environment. By reducing our carbon footprint and transitioning to renewable energy sources, we can mitigate the impacts of climate change and improve air quality. Similarly, water pollution, resulting from industrial discharge, agricultural runoff, and improper waste disposal, contaminates freshwater sources and endangers aquatic ecosystems. Through sustainable water management practices and pollution prevention measures, we can protect water resources for future generations.In addition to safeguarding biodiversity and essential resources, environmental conservation also plays a vitalrole in mitigating climate change. The burning of fossil fuels for energy production is the largest contributor to greenhouse gas emissions, which trap heat in the Earth's atmosphere and cause global warming. The resulting climate disruptions, including rising temperatures, extreme weather events, and sea-level rise, pose significant challenges to human societies and natural ecosystems. By promoting renewable energy sources, increasing energy efficiency, and implementing climate adaptation strategies, we can reduce our carbon footprint and build resilience to climate impacts.Moreover, environmental conservation is closely linked to human health and well-being. Exposure to environmental pollutants, such as air and water contaminants, pesticides, and toxic chemicals, can have adverse effects on human health, leading to respiratory diseases, cancer, reproductive disorders, and neurological impairments. By minimizing exposure to harmful pollutants and promoting clean and healthy environments, we can protect public health and enhance quality of life.In conclusion, environmental conservation is a multifaceted endeavor that encompasses the preservation of biodiversity, the protection of essential resources, the mitigation of climate change, and the promotion of human health and well-being. As stewards of the planet, it is our responsibility to adopt sustainable practices, reduce our ecological footprint, and advocate for policies that prioritize environmental protection. By working together to conserve and restore the environment, we can create a sustainable future for all living beings on Earth.。
environmental protection演讲稿Environmental ProtectionGood morning/afternoon, dear friends!Today, I would like to talk about a topic that is of great significance to all of us – environmental protection Our environment is the foundation of our existence and the source of our wellbeing However, in recent decades, we have witnessed a rapid deterioration of the environment, which poses a serious threat to our future and the survival of countless species on EarthLet's first take a look at the current state of our environment The air we breathe is polluted, filled with harmful substances such as particulate matter, sulfur dioxide, and nitrogen oxides This has led to an increase in respiratory diseases and a decline in the overall quality of our health The water resources we rely on are also contaminated Industrial wastewater and agricultural runoff have polluted rivers, lakes, and even underground water, making clean water increasingly scarceMoreover, deforestation is another major problem Vast areas of forests are being cut down for various purposes, resulting in the loss of habitat for countless animals and plants This not only disrupts the ecological balance but also contributes to climate change as forests play a crucial role in absorbing carbon dioxideThe excessive use of fossil fuels has led to a significant increase in greenhouse gas emissions, causing global warming and climate changeMelting glaciers, rising sea levels, and more frequent extreme weather events are all consequences of this We can see the impact of these changes in various parts of the world, from floods and droughts to heatwaves and wildfiresSo, why should we care about environmental protection? The answer is simple: for our own survival and the wellbeing of future generations A clean and healthy environment is essential for our physical and mental health We need fresh air to breathe, clean water to drink, and a stable climate to grow food and lead a normal lifeEnvironmental protection also has economic benefits A sustainable environment can promote the development of green industries such as renewable energy, which can create new jobs and drive economic growth On the contrary, environmental degradation can lead to losses in agriculture, tourism, and other sectors, imposing a heavy burden on the economyWhat can we do to protect the environment? Each of us can take small but meaningful actions in our daily lives For example, we can reduce energy consumption by turning off lights and appliances when not in use, and choosing energyefficient products We can also minimize waste by practicing recycling and avoiding singleuse plasticsIn terms of transportation, we can choose public transportation, bike, or walk whenever possible instead of relying solely on private cars This helps reduce air pollution and traffic congestionAt the community level, we can participate in environmental protection activities such as tree planting and cleaning up public areas We can alsoadvocate for stronger environmental policies and hold governments and businesses accountable for their environmental impactBusinesses have an important role to play as well They should adopt sustainable practices in their production processes, reduce emissions and waste, and develop environmentally friendly productsFinally, governments need to formulate and enforce strict environmental laws and regulations They should invest in environmental protection projects and promote international cooperation to address global environmental challengesIn conclusion, environmental protection is not just a responsibility but a necessity for all of us Every small action we take counts and can make a difference Let's work together to protect our planet and create a sustainable future for ourselves and generations to comeThank you for listening!。

environment_演讲稿英文回答:Protecting the environment is a crucial issue of our time that demands immediate action from all corners of society. From reducing our carbon footprint to conserving precious natural resources, each of us has a responsibility to play in safeguarding the planet for future generations.Climate change is one of the most pressing environmental challenges we face today. The burning of fossil fuels releases greenhouse gases into the atmosphere, trapping heat and causing a rise in global temperatures. This, in turn, leads to more frequent and intense natural disasters, such as hurricanes, floods, and droughts.To mitigate climate change, we need to transition to renewable energy sources, such as solar and wind power, and reduce our reliance on fossil fuels. We also need to invest in energy efficiency measures to reduce our overall energyconsumption.Deforestation is another major environmental problem. The clearing of forests for agriculture, logging, and other purposes results in the loss of habitat for countless plant and animal species. It also contributes to climate change by reducing the amount of carbon dioxide that is absorbed by the atmosphere.To protect forests, we need to support sustainable forestry practices and reduce our consumption of paper and other wood products. We can also choose to purchase products that are certified by organizations such as the Forest Stewardship Council (FSC), which ensures that they come from sustainably managed forests.Pollution is a major threat to both human and environmental health. Air pollution, caused by the burning of fossil fuels and industrial processes, can lead to respiratory problems, heart disease, and cancer. Water pollution, caused by the discharge of untreated sewage and industrial waste, can contaminate drinking water suppliesand harm aquatic life.To reduce pollution, we need to invest in clean energy technologies and promote sustainable transportation options. We also need to regulate industrial emissions and invest in wastewater treatment plants.Overconsumption is another major environmental problem. The constant pursuit of material goods leads to thedepletion of natural resources and the accumulation of waste. To address overconsumption, we need to reduce our consumption of non-essential items and choose products that are durable and sustainable. We can also donate unwanted items to charity or recycle them instead of throwing them away.By taking these steps, we can all help to protect the environment for future generations. It is ourresponsibility to ensure that the planet remains a healthy and vibrant place for all.中文回答:保护环境是我们这个时代至关重要的问题,需要社会各界立即采取行动。

环境英语演讲稿Hello everyone!Today, I am honored to stand here and talk to you about a topic that is closely related to our lives the environmentLet's take a moment to think about the world around us We live on a beautiful planet, but unfortunately, our actions have been causing harm to it The air we breathe is not as fresh as it used to be The once clear rivers and lakes are now polluted Forests are disappearing, and countless species of animals and plants are facing extinction This is not the world we want to leave to our future generationsThe problem of environmental pollution is becoming increasingly serious Factories discharge a large amount of waste gas and wastewater, causing the air and water quality to deteriorate The use of cars and other means of transportation also emits a lot of harmful gases, contributing to air pollution and the greenhouse effect The excessive use of pesticides and fertilizers in agriculture leads to soil pollution and affects the quality and safety of agricultural productsThe deforestation is another serious problem Forests are called the "lungs of the earth", but we are cutting down trees at an alarming rate for various reasons such as construction and logging This not only leads to the loss of habitat for many animals and plants but also affects the balance of the ecosystem and increases the risk of soil erosion and natural disastersThe loss of biodiversity is also a matter of great concern Due to human activities such as habitat destruction, illegal hunting, and climate change, many species are disappearing from the earth forever This not only weakens the stability of the ecosystem but also deprives us of precious natural resources and potential benefits from biological diversityHowever, we should not be discouraged There are many things we can do to protect the environment Firstly, we can start from our daily lives For example, we can reduce the use of disposable products, save water and electricity, and classify garbage for proper disposal Secondly, we should support and promote the development and use of clean energy such as solar and wind power to reduce our reliance on fossil fuels Thirdly, the government and enterprises should strengthen environmental protection measures, enforce strict environmental regulations, and invest in environmental protection technologies and projectsEducation also plays a crucial role in environmental protection We need to educate people, especially the younger generation, about the importance of the environment and how to protect it By raising environmental awareness, we can encourage more people to take action and make a differenceIn conclusion, protecting the environment is not only the responsibility of a few individuals or organizations but the responsibility of all of us We need to act now, make changes in our daily lives, and work together to create a sustainable and beautiful future for our planet Let's take action and make our world a better place for ourselves and for future generationsThank you all for listening!。
environment作文英文The environment is something that affects us all. It's not just about the trees and the animals, but also aboutthe air we breathe and the water we drink. We need to take care of the environment because it's where we live, and if we don't take care of it, it won't take care of us.The environment provides us with so many things that we often take for granted. The food we eat, the water we drink, the air we breathe all of these things come from the environment. If we don't take care of the environment, we won't have these things anymore.There are so many things that we can do to help the environment. We can recycle, use less plastic, and try to use less energy. These small changes can make a big difference in the long run. It's important for each of usto do our part to take care of the environment.It's not just about what we can do as individuals, butalso what governments and businesses can do to help the environment. They can create laws and regulations to protect the environment, and they can also invest in renewable energy and sustainable practices.The environment is something that we all need to take care of. It's not just about the present, but also about the future. If we want to have a healthy planet for future generations, we need to start taking care of the environment now.。
关于环保的英语演讲稿五篇地球是我们唯一的家园,离开了她,我们别无去处。
为了自己,也为了子孙后代,让我们立即行动起来,投入保护环境、拯救家园的战斗吧!让地球母亲更好地造福于子孙后代吧!一起来看看关于环保的英语演讲稿五篇,欢迎查阅!关于环保的英语演讲稿1Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.关于环保的英语演讲稿2There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put thepopulation planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.关于环保的英语演讲稿3It is very important to deal with the rubbish in cities. Rubbish must be thrown away or reused properly. Or it may cause a lot of problems. It may pollute the air and water. People may get ill when they breathe the polluted air or drink the polluted water.Our city has started to face the problem. Some rubbish is sorted and sent to a certain place .Waste gas is cleaned before it goes into the air. Waste water is also cleaned before it is poured into rivers.People should be prevented from throwing rubbish everywhere. We should try our best to take care of our environment and fight against pollution.关于环保的英语演讲稿4It’s our duty to protect our environment. More and more people ride bikes when they go out nowadays. It’s helpful to keep the air clean.I usually ride to school. I only take a bus on a rainy day. On my bicycle I can breathe the fresh air and do some exercise to keep healthy. On the other hand, I can keep away from the traffic jam and make sure I can arrive at school on time. To my joy, I can also do a bit for keep the air clean by riding a bicycle.I hope everybody will join us and take care of our environment in this way. I believe the air around us will be cleaner with the help of us all.关于环保的英语演讲稿5Many people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our environment. Though the environment doesn’t have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result,the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!What we are suffering is only a small part of what the nature once suffered. If we don’t take action to show respect to the environment, we will have to face an increasingly awful situation.Measures should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.Harmony with the environment is that we live in on Earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and themountains on Earth, the animals.Plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. Therefore, the environment must be linked with social ethics, character education and practice acts as an important element of it. Everyone must fulfil its responsibilities and obligations to protect the environment.。
GAC008 Assessment Event 4: Academic Research EssayA Relevant Environment IssuesStudent‘s Name: Mark LiStudent ID#; 14Teacher: Mr. BuffingtonDue Date: 2013/1/4Word Count: 1234Topic = A Relevant Environment Issues-hypoxia♐main reasonsa.Natural causesb. Human reason♐pollutantsa.Pollution of gasb.Suspended matteR♐impacta.Personal healthb.Ecological systemc.Sociology♐how to reduce air pollutionAir pollutionAir pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.The air pollution can be divided into natural and man-made two reasons. Volcano activity by the release of the smoke will cause air pollution, from desert regions lack of plant blowing sand can cause air pollution from animal, discharge of toxic gases, such as cattle in the digestion of food by the emission of methane will also affect the air quality. These cause air pollution factors are known as natural causes. Of cause, we all know that, in addition to these reasons, the human pressure on air pollution have huge caused. The air pollution is usually due to combustion of fuel causes, However, a lot of resources being consumed, excessive livestock caused by dust or farming generated by the chemical residue burning straw, cut down trees, general industrial activities, the use of vehicles and aircraft, the burning of fossil fuels caused by pollution, paint or other solvents, aerosol, secondhand smoke, burn paper money, These are caused by anthropogenic causes of air pollution.I’ve prepared short speech about our environment. You probably know something about air pollution but I’m going to tell you something more.We often hear phrase: ‘I’ll go out for a breath of fresh air’. But how many of us realize that this has become irrelevant in today’s world, because the quality of air in our cities is realy bad.The moment you step out of the house and are on the road you can actually see the air getting polluted; a cloud of smoke from the exhaust of a bus, car, or a scooter; smoke billowing from a factory chimney, fly ash generated by thermal power plants, and speeding cars causing dust to rise from the roads. Natural phenomena such as the eruption of a volcano and even someonesmoking a cigarette can also cause air pollution.Air pollution is aggravated because of four developments: increasing traffic, growing cities, rapid economic development, and industrialization. The Industrial Revolution in Europe in the 19th century saw the beginning of air pollution as we know it today, which has gradually become a global problem.SmogThe term smog was first used in 1905 by Dr H A Des Voeux to describe the conditions of fog that had soot or smoke in it. Smog is a combination of various gases with water vapour and dust. A large part of the gases that form smog is produced when fuels are burnt. Smog forms when heat and sunlight react with these gases. Smog can affect outlying suburbs and rural areas as well as big cities. Its occurrences are often linked to heavy traffic, high temperatures, and calm winds. During the winter, wind speeds are low and cause the smoke and fog to stagnate; hence pollution levels can increase near ground level. This keeps the pollution close to the ground, right where people are breathing. It hampers visibility and harms the environment. In fact, in the early part of the 20th century, heavy smog in some parts of Europe resulted in a decrease in the production of natural vitamin D leading to a rise in the cases of rickets. Smog causes a misty haze similar to fog, but very different in composition. In fact the word smog has been coined from a combination of the words fog and smoke. Smog refers to hazy air that causes difficult breathing conditions.Acid rainAnother effect of air pollution is acid rain. The phenomenon occurs when sulphur dioxide and nitrogen oxides from the burning of fuels combine with water vapour in the atmosphere and fall as rain or snow. These gases can also be emitted from natural sources like volcanoes. Acid rain causes extensive damage to water, forest, soil resources and even human health. Many lakes and streams have been contaminated and this has led to the disappearance of some species of fish and it also has extensive damage to forests and other forms of life. It can corrode buildings and be hazardous to human health. Because the contaminants are carried long distances, the sources ofacid rain are difficult to pinpoint and hence difficult to control.Fly ashWith the boom in population and industrial growth, the need for power has increased manifold. Nearly 73% of world’s population installed power generation, of which 90% is coal-based generation with diesel, wind, gas, and steam making up the rest. Thermal power generation through coal combustion produces ash that causes serious environmental problems.Commonly known as fly ash, these ash particles consist of silica, alumina, oxides of iron, calcium, and magnesium and toxic heavy metals like lead, arsenic, cobalt, and copper.THE ENDIn many countries in the world, steps are being taken to stop the damage to our environment from air pollution. Scientific groups study the damaging effects on plant, animal and human life. Legislative bodies write laws to control emissions. Educators in schools and universities teach students, beginning at very young ages, about the effects of air pollution . But it does’ t help. In the world there are still lots of people who don’t care about our environment. We should encourage them to protect it. The world is our home so we should take care of it.We should encourage our family not to use car so often, whenever possible take their bicycle or use public transport.we also should reduce the use of aerosols in the household. and switch-off all the lights and fans when not required.It isn’t hard to do. If everyon e do it, our environment will become more clear.Thanks.ReferencesFang young L (2006), ‘Overcapacity exploitation and overcapacity serious the eutrophication of lakes in China’ [online] Available from:/xwzx/gnsz/gdxw/200706/07/t20070607_11637434.shtml [accessed 5 Jan 2013].Davis, Debra, (2002), When Smoke Ran like Water: Tales of Environmental Deception and the Battle against Pollution, Basic Books, hardcover, 316 pages [online] available from:/wiki/Hypoxia_(environmental)#Causes_of_hypoxia.
