Many liberal arts colleges and liberal arts schools within larger universities have distribution requirements. That essentially means that all students must take a few classes in many types of subjects; students usually do this early on, and it helps them figure out what they want to dive deeper into.
Distribution requirements are just one example of how colleges can structure their curriculums to ensure that students can get exposed to different fields. Other curriculum structures are definitely worth looking into.
You may find that you do not actually want to go further with some of those subjects after taking a college course or two in them (as I did with Economics). If you do, however, find that you want to study all of them, you could double major, or do a major and double minor, or simply take a series of courses in a few of the fields. Also, as previous posters have said, interdisciplinary programs are another solid option you could consider, though you may need to look into those before you apply to the colleges.
