Course Category

Course offered by Graduate School of Environmental Science
Semester/Quarter: 1st Semester
Course Format: Lecture (+ small discussion, field trip, etc.)
Level: 1000-3000 (everybody is welcome)
Credit: 2

Keywords
environments, natural sciences
Course objectives
The course will address five issues in environmental earth sciences:
1) global warming and ocean ecosystems, 2) environmental changes and animal diversities, 3) plants and plant ecosystems in Japan, 4) environmental pollution and remediation, and 5) nanotechnology for environmental sciences
The major objective of this course is to engage students in interdisciplinary discourse by addressing each of these issues.
Course goals
Grasping issues in environmental earth science with various spatial scales, and examining the interdisciplinary discourse by addressing each of the challenges.

Field trip: see the flora list and map
Get gather this lecture room by 14:45
We go to a tiny field trip for watching plants in Hokkaido, if the weather is not so bad. (It was cloudy. No problem for the trip.)
 Keep in mind
Prepare something you need, if you do not like to meet disasters, such as mosquito attack and drizzle.
During the trip, mention the seed dsipersal types of plants.
