Air Pollution
Air
is essential for our existence but unfortunate, it is being polluted in many
ways today. In Bangladesh poisonous exhaust from industrial plants, brick
kilns, old or poor, serviced vehicles and dust from roads and construction sites
are some of the major sources of air pollution. Smoke is the main it for
pollution, We produce smoke many ways. We make for cooking; making bricks and
burning refuse which create smoke. Pitch is melted for mad construction.
Railway engines and power houses use coal and oil and create smoke. Mills and
factories use coal, oil and chemicals. Buses, cars and trucks' use petrol and
diesel. All these create smoke and thus pollute the air. Serious air pollution
occurs in big industrial areas and big cities because there are many mills and
factories and motor vehicles. By taking in polluted air we suffer from various diseases. Even many people die of respiratory
diseases from this pollution every year. We can reduce it by making less use of
motor vehicles. We may also use proper lubricants to lessen the level of pollutants.
We can encourage people to use CNG or LPG for fuelling their cars.
