To, The course teacher, Nishat Sultana & Elora shahab sharmee, Dept. of Humanities, BUET. Sub:- Report submission about sea pollution and its prevention. Dear Madam, I would like to inform you that, I have been successful to complete the report about Sea pollution and its prevention, which you had given me as an assignment. Really it was an interesting one. As it was my first assignment, I had to face some problem at first. But by the cordial help of some of my senior brothers and also some of my friends, I was able to overcome the problem. I have taken majority parts of my information from internet. I also read a few books about this topic. I think my small effort can fulfill your queries about sea pollution. I draw your attention and kind consideration if you find any unexpected mistake in this report as it is my first assignment.

With best compliments, Md. Abdullah-Al-Mamun Student no. 0612003 Dept. of NAME Level 2/Term 1 Date:- Dhaka, 11/10/2008
