Russia's war in Ukraine is starving the world

Ukraine is an agricultural powerhouse. But so is Russia. Between the two they account for almost a third of the world's wheat exports.

The Russian invasion has disrupted planting and harvesting in Ukraine. Sanctions against Moscow, for their part, have restricted shipping — further limiting food supplies.

Who's most at risk? Countries in the Middle East and North Africa that depend on these grain imports, like Egypt.

All this comes as the world was already experiencing record-high food prices due to COVID-related supply chain problems and climate change.

The UN estimates that the disruption to food systems causes by the war will make up to 47 million people go hungry.
