Bogotá, Colombia, is the nation’s capital and its social, cultural, and economic center. At 8,600 feet elevation, its air is thin and with eight million residents its air is dirty. To help decrease traffic congestion and air pollution Bogotans have created a dramatically effective mass transit system instituted Cyclovía: each Sunday they cordon off their downtown and turn it over to bicyclists and pedestrians. Colombians love their coffee and brag about it. Most Colombian coffee comes from the Zona Cafetera to the west of the city. Traveling there gives us a glimpse of the life history of the world’s most popular beverage, coffee.
