As ya'll know, I'm a big fan of changing things one small step at a time. Here's another great grassroots idea from my friend Jeffrey Abramson, who runs the Gen Art Film Festival...
REFUSE THE RECEIPT!!!
"Refuse the Receipt" . . . what an unbelievable amount of paper is wasted and sent to the landfill when stores automatically print out receipts. I'm sure that 99.9% of receipts printed immediately get tossed in the trash. People should have to request receipts (like they should have to request a bag). It's ridiculous that some stores have policies that if they do not just give you a receipt you will get something for free!
So I encourage people to tell store clerks to not print a receipt . . .and if they have to - then refuse to take it - let them watch the receipts pile up in their own trash and maybe they will start to realize what a problem it is!
