@Vanny Thank you for raising this issue here.
As I'm a teacher of English, I'd certainly start with introducing relevant vocablary on each of the goals to provide my students with the language for the discussion. An article or a short video are always good for presenting those. I'd also set a number of questions for research to encourage learners' independent inquiry. Then, a debate or an article or a blog post would conclude students' work. No doubt, such an ambitiuos goal requires very thoughtful planning!
