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.

In some remote areas in Vietnam, some people do not have enough clean water to use. As a result, they have to use the water from the river or hand-digged wells and they contain some substance that affects health. Moreover, water filtration systems are impossible to meet the needs of people. The authority has applied a lot of solutions and actions but it must take a lot of time and efforts to supply clean water to every house. Furthermore, the rivers and lakes are contaminated by factories that pour waste into them. They should have inadequate waste-treatment systems to filter the waste before pouring it into the river and the government should have new strict laws to prevent the firm pour waste into water. Water pollution causes great damage, it causes diseases like cholera, diarrhea and skin diseases. The fatality rate of cholera has risen recently especially the children under 5. Water pollution can destroy farming and kill animals around the source like fish and some aquatic life. Water pollution can kill plant life, plants died when they were irrigated with water containing heavy chemicals.

Nowadays, environmental pollution is a hot issue, causing huge waves in public. There are a lot of scientific studies on this issue. Do you know that the cause of pollution originates from the tasks seeming small in our daily lives such as littering, deforestation, or the direct discharge of smoke from vehicles, factory into the environment without treatment. However, if these actions are repeated many times, gradually, the amount of pollution is increasing and has the opposite impact on our lives. The manifestation of environmental pollution is an increase in the carbon footprint in the air, soil and water, which is a gas that does not sustain life. Environmental pollution is also a direct cause of global warming, leading to a series of phenomena, such as the greenhouse effect, ice caps melting, natural disasters such as droughts, floods, volcanic eruption and so on. The sea level is rising, more and more natural disasters occur, which threaten all species, make some of which be rare or extinct, break the ecological balance on the Earth. Human beings are not exception. We are breathing polluted air, eating unsafe food. In recent years, we have seen a dramatic increase in the number of people suffering from respiratory and digestive diseases. In conclusion, environmental pollution is a matter taking a lot of concern. It is time for us to take action to overcome this current issue, to protect our own lives.

Ngày nay, ô nhiễm môi trường là một chủ đề nóng hổi, gây lên làn sóng trong dư luận. Đã có rất nhiều công trình nghiên cứu khoa học về vấn đề này. Bạn biết không, nguyên nhân của ô nhiễm bắt nguồn từ những công việc tưởng chừng như rất nhỏ trong cuộc sống hàng ngày của chúng ta như xả rác bừa bãi, phá rừng làm rẫy, hay tù khói của xe cộ, các xí nghiệp thải trực tiếp qua môi trường mà không được xử lí. Tuy nhiên nếu những hành động này được lặp đi lặp lại nhiều lần, dần dần, lượng ô nhiễm ngày càng nhiều và tác động ngược lại đến với cuộc sống của chúng ta. Biểu hiện của ô nhiễm môi trường chính là sự tăng lên vè nồng độ carbon trong không khí, đất và nước, đây là chất khí không duy trì sự sống. Ô nhiễm môi trường còn là nguyên nhân trực tiếp dẫn đến sự nóng lên toàn cầu, dẫn đến hàng loạt hiện tượng như hiệu ứng nhà kính, băng tan hai cực, các thảm họa tự nhiên như hạn hán, lũ lụt, phun trào núi lửa,... Mực nước biển ngày càng dâng cao, ngày càng nhiều các thảm họa tự nhiên xuất hiện đã đe dọa đến tất cả các loài sinh vật, khiến một số loài trở nên khan hiếm hay thậm chí là tiệt chủng, gây ra sự mất cân bằng sinh thái trên trái đất. Con người cũng không ngoại lệ. Chúng ta đang hít phải không khí ô nhiễm, ăn những thực phẩm chưa đảm bảo chất lượng. Những năm gần đây, chúng ta chứng kiến con số tăng lên đáng kể những người mắc phải các căn bệnh liên quan đến hệ hô hấp, tiêu hóa. Nói tóm lại, ô nhiễm môi trường đang là vấn đề đáng lo ngại. Đã đến lúc chúng ta phải bắt tay hành động khắc phục hiện trạng này, bảo vệ cuộc sống của chính chúng ta.

People today are exposed to various air pollution. Therefore, they are affected by the harmful effects of pollutants in the air they breathe. There are many causes of air pollution. One of the main causes of air pollution is vehicle traffic. Cars, buses, trucks, motorcycles, scooters and trailers are run on fuel. Burning fuel cars leads to exhaustion of toxic compounds including toxic gases as well as particulate matter. Hazardous gases that are part of exhaust fumes include hydrocarbons, nitrous oxides, carbon monoxide and sulfur dioxide.
Plants also contribute to air pollution. Toxic fumes and smoke generated by factories are released into the air thus causing air pollution.
Similarly, burning fossil fuels such as coal, as well as burning firewood for cooking and farm waste leads to toxic fumes that pollute the air. Burning waste also creates toxic fumes.
Air pollution affects the air that people and all other life forms breathe. People around the world are suffering from respiratory and cardiovascular problems and diseases like cancer affect other organs of the body. Millions of people die every year around the world due to air pollution.
Air pollution is now a serious problem for those living in big, congested, industrialized cities with heavy vehicular traffic.
Air pollution may be defined as the occurrence of any foreign materials or gases such as oxides of carbon, sulphur and nitrogen in the air beyond prescribed limit, which are harmful for man, vegetation, animals or buildings.
The major gaseous pollutants of air are carbon monoxide, oxides of nitrogen and sulphur, hydrogen sulphide, fumes of acids, paints, smoke etc. Major solid pollutants of air are dust particles, of un-burnt carbon, lead, cement and asbestos.
