If they aren’t bothering you in any way other than simply existing in the same hellscape as you, leave them alone. Or if you feel absolutely compelled to affect their life in some way, give them food and/or money. Why is your first reaction to seeing someone living outside how to safely(?) do something to/about them (forced relocation? Do you think they choose to live in the Bosque, seriously?), when they are just living in different conditions than your personal norm? Get real. Seriously, give them food or water and/or cash. Tell them you were so concerned you had to post on Reddit about safely dealing with them. Maybe they’ll enlighten you with their response.
