Environmental problems, ranging from household waste disposal to the global environmental pollution and decreased biodiversity, top the list of the world's most pressing challenges that humankind faces today. Students in our course are to learn scientific basics of such environmental issues. Given that correct knowledge in related sciences is a prerequisite for understanding and addressing these problems, our course curriculum is especially designed for students to acquire basic knowledge in the following five areas of study: chemistry, biology, earth science, geochemistry, and geography. In addition to the core studies, we offer a wide variety of classes in application and practice of the knowledge. We place considerable emphasis on experiment and fieldwork, in which students are encouraged to engage. Students are to decide their majors in their sophomore year, choosing one from the above-mentioned five areas, and they pursue their study of environmental science until they graduate. As for thesis writing, they are given plentiful individual attention as each faculty member looks after two or three students only on the average, providing them with careful and detailed instruction.
