Air pollution is a change in the composition of air. Mainly due to smoke, dust, vapors or toxic gases that cause climate change, adversely affect human health or may damage the natural environment of many other species.

Air pollution is the cause of the risk of stroke, neurasthenia, cardiovascular disease, cancer, and a range of respiratory diseases such as asthma, pneumonia, even lung cancer is increasing. .

Air pollution is divided into two types, including outdoor air pollution and indoor air pollution. In particular, outdoor air pollution is a major factor causing serious impacts on the environment and human health in developed and developing countries. The cause of pollution comes from various sources such as traffic emissions, industrial plants, from agricultural production and some natural causes such as forest fires, desert dust, volcanoes.

Besides, we also face indoor air pollution. Pollution sources include cigarette smoke, charcoal, wood, chemicals in paint or cleaning products, air-conditioning gases and some substances in construction materials.

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.

Noise pollution is a very special type of pollution.

(Definition:) It is known to be the exposure to some high sound levels that may lead to adverse effects in humans or other living organisms. (Causes:) Noise becomes harmful when it exceeds 75 decibels (dB), such as the sound at a busy residential road. Noise is painful when above 120 dB, such as the sound of a jet taking off. (Effects:) Noise pollution affects not only the hearing but also the nervous system. It can make us deaf or have high blood pressure, nervousness, hearing loss, and sleep disturbances.

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.

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.

Air pollution refers to the phenomenon of harmful compounds in the form of gases and fine particles discharged into the air thus causing pollution. If the air is contaminated we cannot breathe fresh and clean air. This affects people's lives and all other life forms. People suffer from different respiratory and heart 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 from diseases related to air pollution every year.

Air pollution is caused by a number of factors. Traffic taxi is one of the causes of air pollution. When vehicles travel on the road, burning car fuel, whether it is diesel or gasoline, results in the creation of toxic gases that are released through vehicle exhaust pipes. These gases, in the form of smoke and smoke, seriously pollute the air. Various alternative fuels such as natural compressed air such as automotive fuels are being used today. Battery-powered vehicles are also running.

Plants also contribute to air pollution in a large way. When different manufacturing processes are implemented in factories, they release smoke and smoke. These are then released into the air. We saw black smoke emanating from the chimney or exhaust tower of factories.

Smoke is also caused by burning fossil fuels such as coal. Burning of farm waste and other waste, as well as construction activities also leads to air pollution.

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.
