Hi Noah! For film, I would recommend starting with the basic film courses such as Intro to Film, Film History, Film Genres, and Production to get a feel for what film studies is all about. Production will explore different types of filming for different genres. Once that foundation is set, start narrowing your focus! Nature can correlate with documentaries, TV, and/or movies, so tailor your coursework to what personally appeals to you.
Depending on where you go for film (major, school, or college), there may be mandatory courses to take to declare/graduate the major. Definitely have a conversation with your college and major advisors to see what works best for your graduation/career track. Maybe even gathering some internship or volunteer opportunities if courses aren't available! Your major advisor would know more about those outlets.
Hope this helps! If you have any other questions, feel free to ask.
