There was this bit of government campaign a while ago, titled "the one that creates the mess should pay for cleaning it up" (not in the UK, obvs.)
I, and many with me, pointed out that we're not actually the ones creating the mess. Manufacturers are creating the mess. We already do as much as we can to reduce our use of plastic, but manufacturers pack stuff in so much plastic that essentially, we are paying for their mess.
The campaign didn't run very long, but manufacturers are still the ones creating the mess.
If I buy taco shells, they're in 3 layers of plastic wrap. Cucumbers in plastic, courgettes in plastic mesh, it's ridiculous.
I'd love to go back to glass bottles, our own bags and the like. Like it was when I was a littl'un.
