Environmental interest

[Quad18star]

So I'm taking a course which deals with Environmental Principles and thought this might interest a few people. It's a sensible approach to issues that affect the world .. everything from fossil fuel reserves , to renewables , to global warming. If you're into this kinda thing ... it's a good 50 minutes of video.
