For 2017 it seems like every conservation and environmental organization I contribute to sent me a calendar. And a whole bunch of other paper.
I wish they would stop sending unsolicited calendars, labels, bags, postcards, etc. etc.
This seems like a huge waste of both funds and natural resources and a big contribution to the waste stream. Yes, I recycle everything I can, but even that process uses and energy and resources.
Make the calendars and other things opt-in for those who want them, and otherwise use my donation for the purpose it was given.
