PARAGRAPH ON AIR POLLUTION 1

Humans are today exposed to air pollution of all kinds, and affected by the harmful effects of the pollutants in the air they breathe. There are many causes of air pollution. One of the causes is vehicular traffic. Smoke generated by factories is also let out into the air. The burning of fossil fuels like coal also leads to harmful smoke.

The high levels of air pollution cause respiratory and cardiac problems, and affect other parts of the human body. It also causes other diseases like cancer. Millions of people around the world die each year due to air pollution.

PARAGRAPH ON AIR POLLUTION 2

All terrestrial life forms need air to breathe. We breathe in oxygen from the air and breathe out carbon dioxide. Air pollution is the phenomenon of harmful compounds in the form of gases and fine particles being let into the air thus polluting it.

Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes various diseases, including cancer, affecting other organs of the body.

Vehicular traffic is one of the causes of air pollution. The combustion of the automobile fuel, whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. In factories too when production processes are carried out, smoke is generated that is then released into the air leading to pollution. Smoke is also caused due to the burning of fuels like coal. Construction activity also causes air pollution.

PARAGRAPH ON AIR POLLUTION 3

Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution. One of the major causes of air pollution is vehicular traffic. Cars, buses, trucks, motorbikes, scooters and rickshaws are run on fuel. Automobile fuel combustion leads to the exhaust of poisonous compounds that include noxious gases as also particulate matter. The harmful gases that are part of exhaust fumes include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.

Factories also contribute to air pollution. The poisonous smoke and fumes generated by factories are released into the air thus polluting the air.

Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke polluting the air. The burning of garbage also creates harmful smoke.

Pollution of the air affects the air that humans and all other life forms breathe. People around the world are suffering from respiratory and cardiac problems, and diseases such as cancer affecting other organs of the body too. Millions of people die each year around the world due to air pollution.

PARAGRAPH ON AIR POLLUTION 4

Air pollution refers to the phenomenon of harmful compounds in the form of gases and fine particles being released into the air thus polluting it. If the air is polluted we cannot breathe fresh and clean air. This affects the lives of humans and all other life forms adversely. Humans suffer from various respiratory and cardiac conditions due to air pollution. Air pollution also causes diseases affecting other organs of the body. It also causes cancer. Millions of people around the world die to air pollution-related diseases each year.

Air pollution is caused by a number of factors. Vehicular traffic is one of the causes of air pollution. When vehicles ply on the roads, the combustion of the automobile fuel, whether it is diesel or petrol, leads to the creation of poisonous gases that are released through the exhausts of the vehicles. These gases, in the form of smoke and fumes, pollute the air severely. Various alternative fuels such as compressed natural gas as automobile fuel are being used now-a-days. Battery operated vehicles are also being run.

Factories also contribute to air pollution in a big way. When various production processes are carried out in factories, they release smoke and fumes. These are then released into the air. We see black smoke emanating from chimneys or exhaust towers of factories.

Smoke is also caused due to the burning of fossil fuels like coal. The burning of farm wastes and other garbage, as also construction activity also lead to air pollution.

Humans are today exposed to air pollution of all kinds. They are thus affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution.

Vehicular exhausts cause air pollution

One of the major causes of air pollution is vehicular traffic. Vehicles of all kinds have multiplied across the country. Today traffic congestion on roads is very common. During peak and rush hours the traffic snarls are difficult to cope with for motorists and pedestrians. Commuting has therefore become difficult. Vehicles whether they are cars, buses, trucks, motorbikes, scooters or rickshaws are run on fuel. There is a process of fuel combustion that leads to the exhaust of poisonous compounds. It includes noxious gases and particulate matter. The harmful gases include hydrocarbons, nitrogen oxides, carbon monoxide and sulfur dioxide.

There are many causes of air pollution

Factories also contribute to air pollution. The smoke generated by factories is let out into the air thus polluting the air that we breathe. Similarly, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke. Production of electricity is also mostly through the process of burning non-renewable fossil fuels that leave dangerous smoke in the air. The burning of garbage also creates harmful smoke. Construction activity also creates particulate matter that pollutes air.

Air pollution affects us adversely

Today we are witnessing high levels of air pollution that affect the health of man and other creatures. People around the world are suffering from respiratory and cardiac problems, and various other diseases affecting other organs of the body. Air pollution also causes cancer. Millions of people around the world die each year due to air pollution.

The gases that cause air pollution are also greenhouse gases, and have caused global warming and climate change that affect the Earth and its ecology.

Essay on Water Pollution – Essay 2 (250 Words)

Introduction:

The consumption of water forms a large part of our physical health. Aside from this obvious fact, water is an important aspect of our ecosystem. However, for water to perform its various functions, it has to be kept pure as contaminated water would lead to adverse environmental and health consequences.

Water pollution is the introduction of foreign material into our water bodies like lakes, streams, rivers or groundwater. This introduction, 9 times out of 10 is usually a result of human interference. Through various activities, sometimes inadvertently, we pollute our ecosystem with toxic materials dumped into our water.

Causes of Water Pollution:

One of the most popular features of water is also the cause of water pollution. Water is a “Universal Solvent” which simply means that it can dissolve almost any substance. Consequently, it is also why toxic substance mixes with water effortlessly. These toxic materials could be from traceable sources such as factories, farms, sewage etc. They are sometimes less traceable sources such as pollution in the air.

Water Pollution Effect on our Environment:

The first organisms that come in contact with polluted water are creatures living in the water. The effect of water pollution on aquatic animals depends on the kind of material introduced into the water. In extreme cases, it can lead to death of aqua species. It can also lead to a serious disrupting of the food chain. Finally, water pollution can lead to serious diseases in humans such as cholera and hepatitis.

Preventive Measures:

While the obvious way to reduce or eliminate water pollution is to stop industrial waste, doing just that and nothing more would not be enough. Preventive measures such as reduction in plastic consumption, controlling leaks in cars, using fewer pesticides or efficient disposal of chemicals would help us go the extra mile.

About two hundred year ago man lived in greater harmony with his enviroment because industry was not much developed . Today the situation is quite different People all over the world are worried about what is happening to the enviroment because of modern industry and the need for more energy . Newspapers and magazines write about water pollution , air pollution and land pollution .

About two hundred year ago man lived in greater harmony with his enviroment because industry was not much developed . Today the situation is quite different . People all over the world are worried about what is happening to the enviroment because of modern industry and the need for more energy . Newspapers and magazines write about water pollution , air pollution and land pollution .

The word ‘pollution’ means to make dirty or impure which is harmful. Thus, environmental pollution means the pollution of our environment that happens every day. It happens mostly in cities and industrial towns. Their air pollution occurs because of smoke. Any kind of smoke does it. Smoke from mills and factories, motor vehicles and other sources is mainly responsible for it. Again, water in the seas, rivers and canals is poisoned because of the various wastes we throw into them. Insecticides used in crop fields are often washed away into them by rain water. Mills and factories, on the banks of the river, often throw poisonous chemicals into the river water and pollute it. All sorts of sound from microphones, radios, televisions, etc. cause pollution in the environment. This tells upon our hearing and general health. We all should try to develop a civic sense amongst ourselves about it and bring a check to this pollution in our own interest.

Environment pollution isn't a new problem but it's never get old. Nowadays, more and more companies and factories are discharging many kinds of smog. And this makes the Earth becomes more polluted. The water source is also polluted by rubbish, too. Many irresponsible people throw rubbish out without thinking about the environment. We all know many benefits of the environment, why don't we protect it? Let's protect it as soon as possible, saving the Earth is saving our life.

Environment is an essential part of our life. A clean environment is necessary for a peaceful and healthy life. An environment is the natural surroundings which helps human beings, animals and other living things to grow and develop naturally. But nowadays, our environment is disturbing in many different ways. Any type of disturbance in the nature’s balance affects the environment totally. It does not only ruin human lives but also affects on all living beings. We can save our environment with the little step taken by everyone on the earth. We should reduce the amount of waste, throwing wastes properly to its place only…and many other simple ways. It is very important to save environment for human existence. When we protect the environment, we are protecting ourselves and our future as well.

Bài dịch

Môi trường là một phần thiết yếu trong cuộc sống của chúng ta. Một môi trường sạch rất cần thiết cho một cuộc sống yên bình và khỏe mạnh. Môi trường là khu vực tự nhiên xung quanh giúp con người, động vật và những sinh vật sống khác lớn lên và phát triển một cách tự nhiên. Nhưng hiện nay, môi trường của chúng ta đang bị rối loạn bằng nhiều cách khác nhau. Bất cứ hình thức làm rối loạn sự cân bằng tự nhiên nào cũng đều ảnh hưởng đến toàn bộ môi trường. Điều này không chỉ phá hủy cuộc sống của con người mà còn ảnh hường đến tất cả mọi sinh vật sống. Chúng ta có thể bảo vệ môi trường của chúng ta bằng các hành động nhỏ của mọi người trên Trái Đất. Chúng ta nên giàm lượng rác thải, chỉ bỏ rác đúng nơi quy định… và nhiều cách đơn giản khác. Bảo vệ môi trường cho sự sinh tồn của nhân loại là điều rất quan trọng. Khi chúng ta bảo vệ môi trường, chúng ta đang bảo vệ chính bản thân mình và cả tương lai của chúng ta nữa.

Of course, there are all different kinds of environmental problems and I do not know which problem you want discussed. I will write about global warming.

One of the major environmental problems today is global warming. It is caused by an excess of carbon dioxide in the atmosphere. This causes what is known as a "greenhouse effect."

The major effect of this greenhouse effect is to raise the temperature of the world as a whole. If this continues, climate patterns around the world will change. In addition, sea levels will probably rise, which will be bad for low-lying areas.

There are many possible solutions, all of them have to do with emitting less carbon dioxide -- either by using less energy or by finding energy sources that do not emit carbon dioxide.

Most of the air pollution results from the burning of fossil fuels, motor vehicles, factories, aircraft and rockets. This can cause acid rain which damages water, soil, and vegetation. Air pollution also contributes to the greenhouse effect which can lead to a series of environmental problems such as global warming, polar ice melting, rise of sea levels and loss of land.

Water pollution is a result of dumping pollutants such as detergents, pesticides, oil, and other chemicals in rivers, which makes the water unclean or contaminated. Rubbish blockages in rivers can also cause pollution.

Soil pollution is a consequence of human activities that alter ecological factors that cross the ecological boundaries of the communities living in the soil. The land environment is home to human beings and most of the shallow creatures, the foundations for civil, industrial and cultural constructions. Land is a precious resource, people use land resources for agricultural production to ensure food supply for people. But with the pace of population growth and the pace of industrial development and urbanization, the area of ​​arable land is shrinking and land quality deteriorates, the average land area head drops. Parularly in Vietnam, the actual depletion of land resources is very worrying and serious.  What do we need to do to protect the environment? That is the question that every one of us needs to answer. In my opinion, protecting the environment is the responsibility of the whole community. Everyone must have a sense of protection. The green, clean, beautiful environment will make our lives better. From the house to the alley, from the alley to the school etc. The place is also clean and airy, many trees, air will be fresh, health will be guaranteed. That everyone wants. At present, I see my class, our school where the concentration of people, not very clean, garbage also lunged, trees are still less. On the street, there are public trash but few people put garbage in the bin, you do not throw it, making the street scene is not beautiful. To protect the environment, I feel we must always have a sense of environmental protection in parular: Do not throw garbage indiscriminately, do not discharge dirty water into ponds, do house cleaning, alleys, schools, not breaking flowers ... and propaganda for people always have common sense and responsibility for environmental protection.

Nowadays, pollution is a popular term with everyone in the world and air pollution is one type of pollution. The definition of air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. There are some main reasons which cause air contamination such as burning of fossil fuels, agricultural activities, exhaust from factories and industries, mining operations, and indoor air pollution. Air pollution always has bad effects on our life. Harmful gases, dust, and smoke enter into the atmosphere and make it difficult for plants, animals and humans to survive. We also can see some examples of the result of air contamination which occurs around us as global warming, acid rain, and depletion of ozone layer. The effects of air pollution are alarming, so governments over the world should have suitable policies of protecting the environment, especially air quality to create a clean world for our generation in the future.

Tham khảo:Fresh water is the most important source of life on the earth. Any living thing may survive without food for days however it is impossible to imagine life without water and oxygen. The ever increasing human population enhances the demand of more water for purposes like drinking, washing, performing industrial processes, irrigating crops, arranging swimming pools and other water-sports centres. Water pollution is done by the people of all over the world because of increasing demands and competitions of luxuries life. Waste products from many human activities are spoiling the whole water and decreasing the amount of oxygen available in the water. Such pollutants are altering the physical, chemical, thermal, and biological characteristics of the water and adversely affecting the lives inside as well as outside the water.

When we drink the polluted water, harmful chemicals and other pollutants goes inside our body and deteriorates all the body organs functioning and puts our lives in danger. Such harmful chemicals also disturb the lives of animals and plants greatly. When plants absorb dirty water through their roots, they stop growing and die. Thousands of seabirds are killing because of the oil spilling from ships and industries. High level of water pollution is done due to the chemicals coming out of the agricultural usage of fertilizers, insecticides and pesticides. The effect of water pollution varies from place to place upon the type and amount of water contamination. The degradation of drinking water needs an urgent basis prevention method which is possible by the proper understanding and support from the end of each and every person living on the earth

  

Dear Mr ..... ,

I am writing this letter to complain about the factory near our village which has caused much air and water pollution. The factory is dumping a large amount of fumes into the air, which cause the respitory deseases of some villagers. Moreover, the factory also discharges harmful chemical waste into our village lake. It killed a lot of fish and now, no one can use the water from the lake because it is poisonous.

We all think the factory should be responded for their unconcious, dangerous and irresponsible action. We also believe the People's Committee should make the decision of punishing the factory heavily and prohibit them from contaminating the environment again in order to protect the villagers' lives.

We look forward to hearing from you and hope you will give the factory the right punishment.

Yours sincerely,

.........
