Suggestions for Interesting Mailing Lists?

I’ve always found mailing lists a simple, manageable discussion system.

But too often they’re only used for things like development of open

source software.

Anybody have suggestions for active mailing lists that have discussions

on social and environmental topics like sustainability, electrification,

degrowth, and rewilding?

If so, I’d really appreciate your suggestions. You can email me at

velosol@eml.cc. Thank you!
