I admit: I'm far from being as green as I should be. But there are two things I try to be consistent at. The first is recycling. The second is bringing my own bag to the grocery store.
This Trader Joe's canvas bag was the first I bought:
Despite its petite appearance, it actually fits a relatively large amount of groceries -- you'd be surprised. (A general rule of thumb: it will comfortably carry an almost-full basket of groceries.) Just don't spill maple syrup on it and accidentally shrink it in the dryer like I did.
I forgot my canvas bag one day and saw this hanging on the wall:
It's not uncommon that I walk out of Trader Joe's with more than a single bag of groceries (or my single canvas bag overstuffed and bulging), so I thought, why the hell not? And hello, just LOOK at it. Cute, no? Here's the other side:
And even though I reuse Target's plastic bags for multiple purposes, I was on a roll:
These reusable bags are inexpensive (each of the above was under $3), sturdy and generally hold more groceries than your standard plastic or paper bag. AND they are adorable, people (because let's focus on what's really important here -- I mean, plastic and paper bags are SOO five minutes ago).
In conclusion: there's no excuse! USE REUSABLE BAGS!
