1. Do Now: Create a list of all the food you ate yesterday and today and where the food came from?

2. Turn and Talk Where did your food come from? Would you have been able to get that food a different way?

3. Aim: How Is Food Produced?

4. Food Production Has Increased Dramatically Three systems produce most of our food Croplands: 77% on 11% world’s land area Rangelands/ pastures/feedlots: 16% on 29% of world’s land area Aquaculture: 7% Importance of wheat, rice, and corn Tremendous increase in global food production Why do you think there was an increase in food production in the last 50 years?

5. Industrialized Crop Production Relies on High-Input Monocultures Industrialized agriculture, high-input agriculture - heavy equipment - Financial Capital - Fossil Fuels - Inorganic Fertilizers - Pesticides Goal is to steadily increase crop yield Plantation agriculture: cash crops Primarily in less-developed countries Increased use of greenhouses to raise crops

7. Pause…Think…Write Modern industrialized agriculture produces large amounts of food at a reasonable price. But is it sustainable? Support your answer with evidence.

8. Read A Loud: Hydroponics: Growing Crops without Soil

9. Case Study: Hydroponics: Growing Crops without Soil Hydroponics: growing plants in nutrient-rich water solutions rather than soil Grow indoors almost anywhere, year-round Grow in dense urban areas…roof tops…underground with artificial lighting (Tokyo)… floating barges. Recycle water and fertilizers Little or no need for pesticides No soil erosion Takes money to establish Help make the transition to more sustainable agriculture

10. Summary: Do you thin hydroponics will replace traditional farming? Support your answer with evidence from the case study.
