Essay Dialogue About Pollution

Sujon: Hello Jahangir! How are you?

 

Jahangir: I am fine. What about you?

 

Sujon: I am fine too. But I am somewhat worried about water pollution. 

 

Jahangir: Yes, it is very alarming that the water of canals, rivers, and tanks is getting polluted day by day.

 

Sujon: Exactly! This polluted water causes much harm to us.

 

Jahangir: But man is mainly responsible for water pollution. They pollute water by throwing waste into it.

 

Sujon: Yes, farmers also use chemical fertilizers and insecticides in their fields. Rain and floods wash away some of the chemicals.  

Jahangir: Right you are. And these chemical fertilizers and insecticides get mixed with the water of canals, ponds, and rivers, and thus pollute water.

 

Sujon: Mills and factories also pollute water by the waste materials.

 

Jahangir: Exactly! Leaking of oil from water vehicles, dead bodies, and rotten debrises of animals and plants also contribute much to water pollution.

 

Sujon: Besides, germs of diseases and insanitary latrines are other factors that pollute water.

 

Jahangir: So, it is high time to stop water pollution. But how can we prevent water from being polluted?

 

Sujon: Water pollution can be prevented in many ways. But the main way is to make people aware of the importance of pure water.

 

Jahangir: I am agreed with you. There is no alternative to make people aware of the bad effects of water pollution.

 

Sujon: Thank you very much for discussing such an important issue.

 

Jahangir: You are most welcome. See you again.

The increase in the emission of substances that contaminates the air will eventually lead to air pollution.

A       : Air pollution is both natural and human-based. Natural air pollution is caused by phenomenon such as volcanic eruption, decomposition, and radioactive materials. Volcanic eruptions will send tons of sulphur dioxide and ashes into the atmosphere where it will combine with water particles to form acid rain, while during decomposition, bacteria will release methane and carbon dioxide into the air when it feeds on decaying organic matter.

B : That is true. Meanwhile, human activities or anthropogenic sources also cause air pollution. These activities mostly involve burning of fuels. Stationary sources include factories and power plants. Mobile sources, on the other hand, involve motor vehicles, air crafts and water vessels. Besides, the uses of chemicals in our daily lives such as aerosol sprays containing CFC, or chlorofluorocarbon, also contributes to air pollution.

A : Wow! So there is air pollution occurring almost anytime and anywhere! I am sure that air pollution will do nothing good to all living things and our...
