Interesting you say that. Many journalism programs require a 2nd major or at least minor because it’s considered a ‘soft’ major with minimal job prospects and low pay for most. In other words, you need a back up and some leading journalism programs require this. It’s why I had a double major - required with my journalism degree.
Both my kids are in programs where elective possibilities are minimal. That’s dependent on the major you choose. In your case environmental policy is interdisciplinary so that may give you the diverse coursework you seek. As for gen Ed requirements - maybe look to a Rochester, Brown, Grinnell or one of the schools that have that open curriculum.
I think your expectations aren’t realistic given the major / curriculum you chose. You could have read the required coursework before signing up for the major.
I think it’s going to be hard to make you happy. But I do hope you find that happy place.
Good luck
