This seminar will be held at 3:00pm in S305 of the Student Activities Center. A Wilderness Society instructor is invited to lead the students and teachers to understand the problems facing streams. Human behavior has caused ecological damage, not only to the marine ecosystem, but also to the streams in the mountains and forests. By focusing on the pollution of streams, we realize how our living habits affect the rivers and pollute the oceans, which in turn harms our own health.
