America's Child Migrant Crisis
Increasing numbers of children desperate to reach the US are walking alone across some of the most dangerous and lawless territory in the world. The BBC's Will Grant in Mexico City tells us what's driving them to leave central America. We hear from Western Australia where Phil Mercer tells us about how the city of Perth is defying a chronic lack of rain and warming temperatures. Also, Lucy Kellaway admits she doesn't have much patience with people who are overly familiar or falsely jolly in an attempt to sell you something. All this with our guests Barry Lynn, senior fellow at the New America Foundation in Washington and Revathy Ashok from the Bangalore Political Action Committee.
