One small thing we do for the planet is to always reuse our post packs and boxes.
If you are careful when you open them, they are fine for several uses. Sometimes I even write on them, ‘reuse me!’. It’s much cheaper than buying a new bag or box every time you need to post something as well.
To cover the addresses, I just get a piece of old paper (recycle the back of something!) and write the new address on and sticky tape it over the top. Do the same for the return address. Sticky tape and staples will seal it up well too.
I have a box in one of my cupboards where they all get stored. Post boxes get flattened down to store more easily.
Keep any cute little boxes you get and use those as post boxes too. There is no rule that you have to use a box from Australia Post!
I still remember getting parcels for my birthday from my Granny, wrapped up with brown paper and string! Those were the days!
Is this one small change you could make for our planet?
