Do you keep a re-usable bag handy for those impromptu shops?
If you aren't in this habit already then you could try start today!
I love the eco-bags that you can get at Foodland, each with a different environmental message along with artwork. These are long-lasting and easy on the eye. I keep two in my car to use for shopping and if they come into the house after a shop they are emptied and left waiting at the front door for me until I next leave the house to put them back in the car.
If I go window shopping I take one with me, just in case I make a purchase. Don't be that person who goes into 5 different shops to buy 5 different T-shirts and gets home with 5 different plastic bags. It's just not sustainable...
The more we stop accepting the plastic bags at all shops, not just the supermarkets, the less plastic there will be in the world.
Say NO to plastic!
Re-think your thinking...
