Your paper should be at least 5 paragraphs in length and should also include a literature cited page.
I think paragraph 1 should give you an overview of your environmental issue. Paragraph 2 should detail the problems resulting from this issue. I think paragraph 3 should describe in detail your solution. Paragraph 4 should explain possible issues that may occur, setbacks, etc, from your answer. Paragraph 5 should detail why you selected this issue, problems encountered through your research or the writing process, and at least one thing you learned from this process (content related or personal).
