The essay reflects the kind of research that you did prior to writing the essay. Although you used simple terms to describe your reasons as to why you agree with the statement, your reasons are quite compelling and easily verifiable. That is why your essay makes your stand on the issue clear and also, there is no question about the extent of your agreement with the essay prompt. While you did write a solid essay, I will suggest that you go back and review your use of capitalization, punctuation marks, and also look into the grammar problems present in your essay. Those are the only reasons that the high quality of your paper was diminished. You need to learn to separate the sentences in order to create a readable pause in the paragraph. Without which the reader will have a hard time understanding what you are trying to say. For example:
For instance, most of the cloth production and exports are manufactured in the developing countries, however, hardly people realize the harmful effects caused to the environment by this business
- ... in developing countries. However, people hardly realize the harmful effects...
A review and revision of the paper to clean up those kinds of mistakes will add to the authority and solid discussion of your paper :-)
