There will be a lot of fireworks going off this week and some people are starting to notice an environmental impact. Tune in on July 4 to learn about the impact of 20 years of Rhythm & Booms on the Warner Park wetland. Julia Cechvala, author of an Isthmus article on the topic, will host the show. Talking live in the studio with Julia will be PNMer and Wild Warner member, Jim Carrier. They will discuss the chemicals in fireworks, the debris left over after the show, and the wildlife in the park.
