Every year, whether it's before or after presents, Britons sit down on December 25th and tuck into Christmas dinner. Ritual feast which can be traced back Some 12,000 years later, the food now feels worn out. Turkey, baked potatoes, sprouts, braised pork, piglets in blankets and the rest of the gluttonous chorus join together to sing a song of comfort and tradition. But its future is in jeopardy thanks to the climate crisis. Food production is responsible for about a third of humanity's greenhouse gas emissions. In turn, a changing climate is making it harder to "ensure the resilience of Britain's food supply," the Climate Change Committee, which advises the UK government, has warned. Extreme weather events are damaging crops and can also damage agricultural infrastructure. (GREG BARRADALE)
