Jobs that allow you to explore different areas?

I am going to college to enter into Federal Law Enforcement. However, I am interested in learning about other careers also. I was just curious if there are any decent paying jobs that allow you to travel to other Countries and continents like Malaysia, Australia, South America, Africa, Europe etc. I love the outdoors and wildlife. I would love to get a job that would allow me to travel to different countries. Besides a career in Science is there any job that would allow me to do this?
