পুনর্বিন্যাসকৃত সিলেবাস অনুসারে
Bangladesh is now apparently in the grip of all sorts of pollution like air pollution, soil pollution and water pollution. The dwellers of the urban areas are the worst sufferers of such pollution. The indiscriminate industrialization process in Bangladesh over the past decades has created significant environmental problems. We will now know about some of the most common types of environmental pollutions. Air pollution comes from a wide variety of sources. In Bangladesh poisonous exhaust from industrial plants, brick kilns, old or poorly serviced vehicles, dust from roads and construction sites are some of the major sources of air pollution. We can reduce this type of pollution by making less use of motor vehicles and avoiding the use of vehicles older than 20 years.
