Funny, we were just saying this morning how when we were little you had one aluminium dustbin for the whole week's waste. Now we have 5 bins! It's all down to packaging too!
We never had butter or margarine in tubs - they were blocks, wrapped in greaseproof paper, which folds very small. Milk, beer and fizzy drinks glass bottles were recycled (kids would do this to collect the money- we loved collecting the empties to get a few pence additional pocket money). you bought your fruit and veg loose at the greengrocer - no packaging at all! Clingfilm and shrink wrapping didn't exist and there was no such thing as internet shopping with all the bubble wrap and boxes that entails.
Mars manufacturers have made a start in going "back to have a future". I hope other manufacturers will follow suit. We have come a long way since I was a child and we are very lucky to have such convenience, but some of the old ways could still be adopted to reduce plastic waste.
