Sir, – The answers to our climate crisis may not all be found at Cop 27 in Sharm el-Sheikh. This week in local shops I found beetroot from France, courgettes and onions from Spain, and carrots from Denmark. Surely we could substantially reduce our carbon footprint by meeting as much of our needs as possible locally, if not nationally? – Yours, etc,
