Brazilian President Dilma Rousseff took the stand today in her ongoing impeachment trial. We get the latest on the trial from Peter Prengaman, Brazil news director for the Associated Press. And when he was 11 years old, David Tapper received an award from the Illinois Environmental Protection Agency to work on environmental justice. His focus was on how green roofs. Tapper’s project would eventually lead him to farm his own space with a green roof farming community on top of the parking garage of Chicago’s Weiss Memorial Hospital. Tapper and his mother, an urban agriculture advocate, join us to talk about the rooftop farm.
