Document Summary

Food systems and food waste read professor"s reading. Food system food chain that starts with food production and ends with food waste disposal: feedback loops, industrial food system increase the amount of food produced with the smallest amount of inputs (cost-effective and efficient) Fast growth of cafo animals low doses of antibiotics in feeds facilitate antibiotic resistance in biological pathogens implications for human use of antibiotics. Aquaculture faces the same issues that apply to cafos: most agricultural systems are using some sustainable practices. Lack of food security especially for people in the developing world: if food workers don"t get sick days, there is a higher chance of contaminating the food that they handle and process environmental health problem. Can"t afford to miss work and to go to the doctor for lack of health insurance: cows belch, releasing methane into the atmosphere, and there are also offshoots of methane emissions released from animal waste.
