Bangladesh is now apparently in the grip of all sorts of pollution like air pollution and water pollution. The dwellers of the urban areas are the worst sufferers of such pollution. Th indiscriminate industrialization process in Bangladesh the past decades has created significant environmental problems. We will now know about some of the common types of environment pollution. Air pollution comes from a wide variety of sources. In the Bangladesh poisonous exhaust from industrial plants, brick kilns, old or poorly serviced vehicles and dust from roads 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.
