Go beyond the re-usable grocery bag.
Don't get me wrong, using cloth grocery bags is AWESOME and reduces SO much waste. But why stop there?
If you think about it, disposables are really weird. Why would you buy something just to use it and throw it away? How many thousands of years did humans use and re-use and re-use and re-use something before it was no longer usable?
I challenge you to
bring your cloth bag to the mall
store a few bags in your car
have an open mind
bring your own chopsticks to the restaurant
use the bulk section in your grocery store
ditch plastic straws
bring your own thermos for a coffee
fill up your glass/aluminum water bottle
pack your lunch in tupperware
say "I don't need a bag for that, thank you"
get out of your comfort zone
do your research
and, of course, stop buying things you don't need, use, or love
Let's give the landfills a break, shall we?
