As for the homeless: an empty container weighs a fraction. Of what a full container weighs. Pack it in, pack it out. 
Do you know that housed people manage to find time to work all day. pay bills, do maintenance, socialize, volunteer and a host of other activities that keep us busy all day long. Still, we manage to haul our trash to an appropriate location.
