One needn’t even major in bio to do this. My older daughter did exactly that job for three years, between college and grad school, and she wasn’t a bio major; her degree was in Cognitive Science, with a Sociology minor, and there wasn’t that much bio content in her CogSci curriculum - she knew she wasn’t interested in med school, and did not take the prereqisite classes. What would actually have helped, for the research coordinator job, was a stronger statistics background. The job itself would also have fallen into the OP’s “a desk job would be torture” category.
As a completely different angle to look at… if the student actually loves environmental science (recalling the “studying sea turtles in the Galapagos” remark), a way to tweak that for employability is to acquire a strong skill-set in GIS. Grads with a GIS specialty can get active jobs doing data collection - working outdoors, piloting drones, etc. Some schools, like UConn, even offer full majors in GIS: Geographic Information Science (BA or BS) | University of Connecticut Academic Catalog and one could certainly fulfill pre-health requirements to keep that option open. Not sure if this student would enjoy a major like this, but there are quite a few good programs at varying levels of competitiveness. (Delaware, Hofstra, Clark…) and many more offer it as a minor or certificate that can be combined with a degree in bio, enviro science, etc. I guess one question to ask is, does the student want a career that’s both active and very people-y (i.e. direct patient care) or would she actually prefer active-but-with-fewer-people, as with field work in enviro/marine science, GIS, etc?
Another angle that a lot of suburban kids don’t think of is the whole array of majors that fall within schools of agriculture. Food science, soil science, aquatic/fisheries science, and so on. This also overlaps with what’s offered at enviro-focused schools like SUNY ESF - their list of majors could be worth browsing: Undergraduate Programs
This student sounds like she enjoys working with people, and I’m not in any way trying to dissuade her from pursuing something in the health care sphere; just poking at the other interests that have been alluded to.
