I like the return of the victory garden idea. Just make sure you get heirloom seeds that have not gone through any type of genetic modification for size, color. etc. etc.
I have even gone on a mission of late to bring out all our old stuff out of storage... like the old safety razors and straight razors (yes I have a few) so as to STOP buying disposables or this two - what is it now five blade crap that gets all clogged up and is almost useless. I forgot how well a single blade works.
Anything to find a way to quit buying STUFF. Need and want are two different things, one way to effect change would be to focus on need.
