Hi
I hope you are okay
One of my constant concerns is that shopping receipts are always discarded
Or most of the time people put that receipt in their mouths and then throw it away.
In my opinion, if these receipts come from the bank and the rest of the papers that do not need to be made of the same material,
That one can eat them or use them as gum or at least make one material; so that the rest of the creatures can use that paper. The environment around us is also cleaner and fewer trees are destroyed.
