I won a box of Cadbury's Creations in a local raffle last night and every item was in its own plastic / aluminium foil wrapper. Why?
Chocolate does not go "off" for months, even years. It does not need to be plastic wrapped.
It's the same with many items we all buy every day - crisps, biscuits, cakes, bread, choccy bars. These things fly off the shelves in days. They do not need months long 'best before' or 'sell by' dates, but there they are, all wrapped in plastic. The plastic we bin rather than recycle (if we can be bothered).
We once had cellophane wrappings -a natural and biodegradable film infused in paper - for things like crisps, biscuits etc. now we have plastic. ???
Hell in a hand cart. This crap enters our global environments -air, sea and land. Worry not, though, our fossil fuelled EV SUVs will save us. Net-Zero.
