A startling new figure reported by the Independent indicates that shoppers in the United Kingdom have used a shocking 7. 96 billion single use bags last year, marking an increase of 400 million bags used in total. The article notes that plastic bag usage has increased all across the UK with the exception of Wales and Scotland. Wales, which is subject to a 5p bag tax, has seen a drop in usage of about 22 percent, while Scotland has, despite having no ban at present, dropped usage by a much smaller 0.3 percent.
