  1. Lesson 1: Food glorious food Steps for feeding a population

  2. What is a food system? • All the Processes Involved in Feeding a Population

  3. how big is our population? • World = 7 Billion • U.S. = 313 Million • Colorado = 5 Million • Denver = 600,158

  4. Steps for feeding a population Step 1: Growing Step 2: Harvesting Step 3: Processing Step 4: Transporting Step 5: Marketing Step 6: Purchasing/Consuming Step 7: Waste Disposal

  5. Step 1:growing raw ingredients • Climate Matters • Good Soil is Key! • Rich in Organic Matter* • Starts with Planting Seeds • Fertilize and Water • Plants Grow (Photosynthesis)* • Carbon from Food

  6. definition: organic matter • It was once living. It serves as a reservoir of water and nutrients in the soil. It may come from plant crops, animal manure or wood shavings.

  7. definition: Photosynthesis • Plants use energy from the sun (photo means light) to synthesize or make food.

  8. Real life example:growing tomatoes • Tomatoes like a Warm Climate Grow Best in the Sun • Soil PH should be from 5.5-6.8 Not too acidic or basic • Tomatoes can be grown inside Transferred outside in spring What is PH? PH scale measures the acidity or alkalinity of soil. Range is from 1-14 Less than 7 = Acidic Greater than 7 = Basic

  9. Step 2:harvesting What part of plants do we eat? http://www.teachersdomain.org/asset/lsps07_int_plantparts/ More examples: http://pubs.ext.vt.edu/348/348-823/348-823_pdf.pdf

  10. Step 3:PROCESSING Techniques for transforming raw food into other food products

  11. Step 4:transporting Transporting food from where it is grown to where it is processed or purchased

  12. Step 4:transporting Average Miles Food Travels = 1,500 Miles

  13. Step 5:marketing Strategies used by food makers to entice buyers to purchase a product

  14. Step 6:consumption Purchasing Food Preparing It Eating at Home Dining Out

  15. Step 7:food wastedisposal 14 Million Tons of Food Wasted Every Year • Rots in Landfills Produces Methane Gas Recycling Food = Composting
