Guest: Arif Husain, Chief Economist at World Food Programme

Ukraine was forced to close its four Black and Azov sea ports earlier this week and, as one of the breadbaskets of the world, this cut off access to the country's rich grains. These ports help feed 400 million people, many of whom live in the poorest countries in the world. Even before the war began, global food prices were at an all-time high and now experts fear how the closed ports will add to the global food crisis. Arif Husain at the World Food Programme talks about the consequences.
