It is important for us to see not only the short-term effects of our actions, but their long-term effects as well. Look in the left column of the table for the kind of logical relationship you are trying to express. The image to the left gives you an impression how it looks like.
In providing the reader with these important cues, transitions help readers understand the logic of how your ideas fit together. Transitions cannot substitute for good organization, but they can make your organization clearer and easier to follow.
Transitions are not just verbal decorations that embellish your paper by making it sound or read better. So, in Paragraph A you would enumerate all the reasons that someone might consider El Pais highly democratic, while in Paragraph B you would refute these points.
Whenever you have trouble finding a word, phrase, or sentence to serve as an effective transition, refer to the information in the table for assistance.
Another harm caused by human activity to this earth is pollution. In this case, you should include a paragraph that transitions the reader out of the general information in the first section into the specific experiment in the second section.
