text:  That's all we have time for today. But before we go, we need to say bye to our panel. Thank you, Christine Yohannes in Addis Ababa, Ethiopia. And thank you, Godfred Boifo in Accra, Ghana. Always a pleasure, Alex. I'm Alex Lathbridge, and the producer was Harrison Lewis, with Alice Lipscomb-Southwell, Florian Bohr, and Noah Dowling. Join us next week for more Unexpected Elements.
