Every little helps says Tesco – especially now that they’re planning to reduce the number of plastic bags customers use. This global catastrophe-avoiding scheme will mean that only 75 billion bags will be used by their customers next year. If you’re thinking that 75,000,000,000 placcie bags is still quite a lot, Tesco is quick to point out that the bags will be sunlight-degradable (although not bio-degradable), so no worries there as they sit under mountains of landfill never seeing daylight.
