Air Pollution - Paragraph- Gazi Online School
Air Pollution
Air is very important element (উপাদান) of our environment. No creature (সৃষ্টি) can live without air. It is the life giving force (বল). Clean air is essential (প্রয়োজনীয়) for life but polluted air is very harmful. Air can be polluted many ways. The most common agent (মাধ্যম/প্রতিনিধি) that pollutes air is smoke. Smoke is produced when we cook food, burn (পোড়ানো) bricks (ইট) and refuse (আবর্জনা).
It is also produced when we melt (গলা) pitch (পিচ) for road construction (নির্মান). Many buses, trucks and cars plying (চলাচল) in big cities use petrol,
diesel and oil. When these fuels (জ্বালানি) are burnt, they create smoke and pollute the
air. Mills and factories in large industrial areas also cause serious (মারাত্মক) air
pollution. Railway engines and power houses (বিদ্যুৎ কেন্দ্র) also pollute air. Air pollution causes different types of disease such as asthmas, cardiac disease etc. It is is a big threat to our health and nature. However, it is
really difficult to prevent (প্রতিরোধ করা) air pollution, but it is possible to reduce (কমানো/হ্রাস করা) its
quantity (পরিমান). We can make less use of motor vehicles and avoid (এড়ানো) the use of vehicles
older than 20 years. Again, we can try to increase (বৃদ্ধি) the use of solar energy,
which does not pollute air. Moreover, we have to stop cutting down trees in
large number because trees absorb (শোষন করা) the poisonous (বিষাক্ত) carbon gases from the
atmosphere (বায়ুমন্ডল) and keep the environment good. So, to ensure (সুনিশ্চিত) a healthier and happier
life we must control (নিয়ন্ত্রন করা) air pollution.
