Freshwater Science & Sustainability Major

Hi everyone!
So my university offers this major called “Freshwater Science & Sustainability”. I’m thinking about switching to it, but our advisors here are absolutely awful and have offered no help in giving perspective in potential job market, or what kind of career I could make out of it. I’ve done some research on my own and found a little information (not much), but I was wondering if anyone could offer some added insight into ideas of whether this is something I could actually make a successful career out of, and if there is a real job market for it. I’m in my junior year, so if I make the switch, I need to know that it’s going to be worth it.
Thank you!
