The things that exist around us are called environment. Air, water,
earth, trees, animals, etc are the elements of environment. Our life is
deeply related to the environment. So, any pollution of this environment
causes dangers to our life. Environment is polluted in many ways. Air
is an important element of the environment. Air is being polluted by
smoke and different gases. Mills and factories produce a lot of gases
like carbon dioxide, sulfur dioxide, etc. Many vehicles also produce
smoke and pollute our environment. Water is another vital element of our
environment. Mills and factories, water – vehicles and human beings
through their waste products and rubbish in the water and thus pollute
water. Deforrestation (গাছ নিধন) also causes environment pollution. We are also affected by sound and odour (গন্দ্ধ দুুুষন) pollution. Environmental
pollution badly and seriously affects our life and causes many diseases.
So we should give more care to keep our environment free from
pollution.
