The war in Ukraine has impeded Europe's reliance on Russian gas, leading directly to a global energy crisis. Might a similar thing may be on the horizon for food? Fertiliser is used to grow about half the planet's sustenance. Some are warning that if Russia, which exports more of it than any other country in the world, were to block supplies in a similar manner, the result may be a global food crisis. Svein Tore Holsether, the head of Yara, one of the world's biggest chemical companies, thinks that Russian President Vladimir Putin is "weaponising food". Mr Holsether, who is also the chairman of the industry lobby group the International Fertilizer Association, intends to make clear his concerns to business and global leaders at the World Economic Forum in Davos. He joined us on Newsday. (Photo shows: File photo of empty shelves at a Co-op supermarket, with concerns mounting over a food supply crisis. Credit: PA)
