This week, Pittsburgh-area high school students visited Phipps Conservatory and Botanical Gardens for an eco-challenge to raise awareness of what individuals can do to take care of the environment. They came up with radio spots on environmental topics. They had 10 just minutes to do it. And yet, the results were pretty creative. The Allegheny Front was there to record the students and today we broadcast a few examples from kids from Wilkinsburg, South Fayette, and Moon Area high schools.
