I start by reducing the mail coming in - 'going paperless' on my bills, taking myself off any mailing lists that aren't of particular interest, etc. Whenever I can, I stuff the junk mail into any prepaid envelopes they've sent, and mail it all back to them, lol. Anything with sensitive information becomes a firestarter, bigger items, like
cardboard get repurposed for garden mulch, torn up for critter bedding (
chickens, ducks,
rabbits, guinea pigs...), crafting, or as packing materials to ship things out. Only the plastic that I can't figure out a use for goes to the dump - and even that bugs the piss outta me.
