If he’s outdoorsy or aspires to be, investigate Earth Corps:
https://www.earthcorps.org/join-the-corps/corps-program-overview/
It’s based in the Puget Sound but accepts applicants from around the world. We have relatives who live down the street from an Earth Corps supervisor. A lot of corps members go on to be arborists, wetlands restoration workers, etc and often go on to get college degrees in environmental studies or technical certifications in related fields.
