Total ban on the plastic fasteners used to attach gift tags to clothing/products. This is something I have noticed after receiving gifts over Christmas, all of my gifts used the unrecyclable plastic fasteners.

In the UK we generate 5 million tonnes of plastic each year. Banning this single use plastic would help to reduce that figure. There are alternative tagging materials that retailers can use e.g. string & safety pins, which I have seen some retailers use.
