Science

In the summer of 2023, Bruce Lanphear, Professor of Health Sciences at Simon Fraser University, resigned his position as co-chair of a recently formed Science Advisory Committee of the PMRA, which regulates pesticide use in Canada. Dr. Lanphear felt he could no longer lend his credibility to the agency following disagreement about the Terms of Reference provided to Lanphear and seven other scientists comprising the committee.  Lanphear has been critical of aspects of Canada's pesticide oversight regime. I invited him on the show to discuss the topic.  You can read about Bruce's resignation here and here, or check out this google search.

The US chicken industry is dominated by just a few very large, vertically integrated companies.

After that: the farmer questionnaire! Some links related to the chicken conversation and the proposed rule changes: Patti suggests this blog post for a summary of the rule changes A recent op-ed in Civil Eats about the tournament system Here's an official summary of the proposed rule-changes

The Case for Slower

This episode I speak with Dr. Patrick Byrne, Professor Emeritus of Plant Breeding and Genetics at Colorado State University. Our topic: crop wild relatives, the forebears to all of the agricultural crops we love and depend on. Patrick helps us understand the relationship between, say, Teosinte and modern corn, and why the conservation of these wild relatives is crucial to the improvement of our crop cultivars.  Links:  Grin-U.org: a great repository for online learning materials on plant genetic resources conservation and use.
