Nature's Past Episode 036: Histories of Canadian Environmental Issues, Part VI – Agri-Food Systems, I
Bibliographic record
Abstract
The history of Canadian food and agriculture is an enormous topic with both a global and deeply personal scope. All humans require food to live and agricultural products become food for our consumption, demonstrating the profound interrelatedness of food and agriculture. Beyond sheer survival, food serves social and cultural purposes for all people, from planting and harvesting, through preparation, and ultimately with consumption. Communities and families coalesce around these activities and have done so for all of human existence. Food is a source of pleasure and for many people is intricately linked with spirituality. Examining the environmental history of food and agriculture in Canada reveals the ways in which our complex relationships with nature and each other inform this most intimate aspect of our daily lives. \n \nA primary element of agriculture is a relationship with the earth. In order to cultivate crops to harvest and consume, humans must manipulate the natural environment. Since the arrival of Europeans to North America, agriculture has largely involved a perceived human domination of the environment including physical manipulation (tilling, seeding, deforestation, filling wetlands), technological innovation (genetically modified crops, mechanized equipment, fertilizer, pesticide), and transportation of agricultural products (railways, highways, airports, canals and seaways). Euro-Canadian concepts of liberalism have also influenced the relationship between people and the planet, promoting private property ownership as one of its foundational elements of property, liberty, and equality. The ideal of the yeoman farmer, an entrepreneurial agricultural producer, is fundamental to the Canadian founding myth. In order to create Euro-Canadian farms on the landscape, however, indigenous peoples were displaced, intertwining human relationships with the land and also with other humans. \n \nFood and agriculture require and inform our relationships with each other. In the process of colonialism, European-style agriculture was adopted by and foisted upon indigenous peoples through political mechanisms. Politics, food, and agriculture continue to be closely tied as demonstrated through food-based political movements, agricultural and food regulation and legislation, international trade policies, and even in Canada’s World War I conscription crisis. Migrations between provinces and immigration policy have been driven by agriculture, and current Canadian politics are focused in many ways on increasing the export of Canadian agricultural and food products. Regional and national dishes and crops inform Canadian identities. The power shift from producer to corporation in Canadian food systems is thought to be a factor in social inequity experienced by people across the globe. \n \nCanadian agriculture and food are crucial components to discussions about health. The quantity of food available dictates both famine and obesity, as does the quality of food. As more is known about the health effects for humans of genetically modified foods, hormone-added foods, chemical fertilizers and pesticides, and food-borne infections such as Escherichia coli and bovine spongiform encephalopathy, we are changing how we interact with our food and its suppliers. Agricultural environmental practices also raise concerns about the health of the groundwater we drink and use for irrigation, as well as the air we breathe. Reviewing the history of agriculture and food in Canada helps us understand why we have the systems we do and how they came to be, as well as assess their efficacy for our contemporary needs and desires as humans always in need of nourishment. \n \nTo begin this look at agriculture and food in Canadian history, we look at the case study of chicken breeding in North America in the nineteenth and twentieth centuries. On this episode of the podcast, we spoke Margaret Derry about her new book Art and Science in Breeding: Creating Better Chickens. \n \nMargaret Derry's new book Art and Science in Breeding: Creating Better Chickens. \nPlease be sure to take a moment to fill out a short listener survey here.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
