In this environmental studies class, we wrote quite a bit.
We had weekly blog posts summing up the week's material (and in my case, opining about it) and a research paper.
The blog itself can be found here if you'd like to navigate it yourself, but I've also assembled an archive of its posts to go on this website so you can read all the posts in one place.
My research paper, which covers the carbon tax, can be found here.
