Don't buy shit you don't need, reuse what you can, recycle, what's left, stop eating so much meat and dairy (especially red meat) or stop entirely, switch to !micromobility@lemmy.world over a vehicle if you can, if you have a house get your insulation done, switch to solar, next time your HVAC dies, replace it with a heat pump, avoid non-local products where possible, buy sustainable, and consider volunteering in meaningful ways.

Once the solar punk instance comes back up, check them out: I think you will appreciate a lot of their communities: slrpnk.net
