Sharon Pochron studies earthworms and how they react to various stressors, including the weedkiller Roundup. Host Heather Lynch and Pochron, an assistant professor in the School of Marine and Atmospheric Sciences, discuss how this weedkiller and others affects the health of both humans and the organisms that dwell within the soil. Pochron also discusses the current concerns that undergraduate students have about the environment and how the water fern Azolla may be the key to mitigating greenhouse gases.
