Firefighters test out new tool as Brazil's Pantanal wetlands burn

Record-setting wildfires are raging in Brazil's Pantanal region. In a densely vegetated rural area the size of England, it can be hard for firefighters to find and reach the blazes to combat them. That's why one nonprofit is training local fighters to use drones to pinpoint the exact location and size of fires, and scope out roads to reach them. The World's Carolyn Beeler reports from the area.
