Eluned Morgan CARDIGAN and Teifi valley residents and visitors are being asked to cut back on plastic use following this year's Plastic Free campaign. Across the globe, 326 million people signed a pledge in July to take action in their own lives to reduce the use of plastic drinks bottles, bags and straws. During the recent heatwave, shops and supermarket shelves were emptied of bottled water and other soft drinks as convenience came before the environment as temperatures soared. The Met Office has said that the effects of climate change are already being experienced in the UK as 2020 was the warmest, wettest and sunniest year since records began.
