Adventurers Question:

Recreation workers, trail guides, scuba instructors all have salaried positions you can get with the proper experience and certifications. The experience you have gleaned from traveling abroad, adventuring on your own, or studying in your desired field should open up a variety of options doing the type of thing you want to do. Get a job with the state at your favorite park, or start your own business teaching kayaking lessons.
If you are getting paid to teach other people about what you love, every day can be an adventure. Get a job at a ski resort teaching snowboarding lessons, or work your way up at an aquarium. You do not necessarily have to be a marine biologist to work with animals.
