Need help understanding what to study

Hello I(20), have always been interested in nature interacting with plants and animals since I was a child but in HS I was offered to go to a tech school for ag where I studied envi sci, horticulture, and equine but left my senior year for full time hs because of racism and bullying I encountered there. Since I graduated my interests and focuses have changed a lot, I'm really interested in many topics such as, stream and forest regeneration, Brad Lancaster's work with urban rainwater harvesting, rain gardens, regenerative agriculture, indigenous agricultural methods and their role in sustainability/conservation, I'm also interested in horticulture relating to native plants I thought I may as well take a business class on the side in case I ever want my own nursery. But to get the point of my problem, I have only recently finally gotten the chance to get a college education without accumulating debt and I don't really know what to study with everything I'm interested in, what are some degrees and career paths I should do research on so I can figure out what I want to pursue?
