The advantage of including text-based sources in your research is that written products generally delve more deeply into the issues. There are also many more text-based sources available, and they represent a wider range of types, authors, and perspectives. Read at least three text-based sources from the list below. As you read, notice how each source adds to (or changes) your understanding of the beginning of environmentalism as a political movement.
