Barry and Lucas continue their Quar-ing Twenties series with another really smart and hopeful guest. Ed Avol is a Professor of Clinical Preventive Medicine, with expertise in exposure assessment and acute/chronic respiratory and cardiovascular effects of airborne pollutants in populations at risk. He was also part of BARACK OBAMA’S Clean Air Act commission. Remember Obama? He was one of the people who helped rid LA of it’s smog problem in the 90s and has a lot to say about the many ways our environment affects our health, good ozone vs. bad ozone, how farts might be killing us and why this pandemic could lead to action in climate change.
