In this May 17, 2017 photo, cowboys chat as they eat a "churrasco," or barbecue, at a ranch in Corumba, in the Pantanal wetlands of Mato Grosso do Sul state, Brazil. Each day, the men and animals traverse about 11 miles from dawn until 3 p.m., in temperatures averaging about 90 degrees Fahrenheit during the day. (AP Photo/Eraldo Peres)
