How to make a Literature and Environment course interesting and engaging for undergraduates?

I am going to teach a Literature and Environment course for undergraduate students in the upcoming semester. The syllabus includes some fictional readings, environmental cartoons, and non-fictional/ eco-activist writings related to various ecological disasters.

Most of the students are from non-literary undergraduate courses such as business studies and computer science. While some students might have chosen this course to fulfil their syllabus requirements, I want to keep them interested in the classes and make it a valuable experience for them.

I am looking for suggestions and ideas to ensure that this is not just another course that students pass without being actively engaged. I'm considering the possibility of watching documentaries in the class and discussing local issues that the students are familiar with, but I would like more suggestions. If you were taking this course, what would you want to learn? If you have taught such a course before, what did you do to make it worthwhile?

Also, suggest some environment-related documentaries as well if you can.
