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.Learn more with:“Current and future glyphosate use in European Agriculture”“Effects of glyphosate exposure on intestinal microbiota, metabolism and microstructure”“Exposure to aged crumb rubber reduces survival time during a stress test in earthworms (Eisenia fetida)” by Sharon Pochron, Jacqueline Nikakis, Kyra Illuzzi, Andrea Baatz, Loriana Demirciyan, Amritjot Dhillon, Thomas Gaylor, Alexa Manganaro, Nicholas Maritato, Michael Moawad, Rajwinder Singh, Clara Tucker, & Daniel VaughanThe Farm BillThe 4/1000 InitiativeSkip ahead to the chapter that interests you:00:00 Introduction to Roundup03:16 Roundup’s Effects on Soil and Human Health06:42 The Wheat Farmer’s Use of Roundup09:16 Fast vs. Slow Microbial Turnover10:21 The Benefits of Using Roundup12:32 Roundup’s Effects on Earthworms14:20 Earthworms and Their Impacts on Soil Health19:14 Undergraduate Concerns for the Environment25:11 Additional Concerns27:02 Azolla as a Sequestration System  33:02 Conclusion and Final ThoughtsTell a friend and share a link to this episode.You can find all our episodes at www.stonybrook.edu/c4e or wherever you stream audio.Sign up for our newsletter: https://www.stonybrook.edu/commcms/c4e/newsletters.phpFor all things Stony Brook on social media: https://bit.ly/m/sbuC4E Presents is a production of Stony Brook’s Collaborative for the Earth.Host: Heather LynchEditor: J.D.
