RJA #3b: Narrowing Research Topic

As of right now I need to narrow my topic because there are so many controversial effects of dam removal. I could talk about the political and economical side to the issue, or the geologic effects including the sediments changes, or the river itself with flow and temperature or I could focus on the ecological effects mainly animals and plants. I plan to look into each one of these topics more to see which interests me the most with a lot of information to base my paper on. Then I will pick one or two related topics to begin to reasearch in depth.
