Lots of good suggestions.
Do you like working around a lot of people, with people at all? Or something solitary? Indoors or outdoors? City or country? What kind of climate do you prefer? I mean, if you're going to pick something, try to look at the whole picture. Where do you want to live and spend your time? Do you want to travel? Do you want a family?

Environmental Science is getting quite a bit of attention. If you like Nature, or biology, this might be an area to consider. Global warming is becoming a big business and with everyone being mandated to go green, cities and municipalities are looking under rocks for geologists (har-har), biologists, GIS operators, environmental policy makers, hydrologists, etc... just to meet the new requirements.
Water reclamation is fascinating and becoming huge. Then there's all the conservation and preservation stuff. Saving animals from extinction, educating the public, yada, yada, yada.
And if you like animals more than people; Veterinarians, while they have to go to school a lot longer than MD's, have lower overhead costs, especially malpractice insurance. My vet takes home more than my cousin, who is a World-renowned brain surgeon. My vet is uber-rich.
Archaeology is another quiet, solitary, out of the box endeavor.
