  1. Food Production

  2. How is food produced? Industrial Agriculture Traditional Agriculture

  3. Green Revolution Develop monocultures of high-yield key crops Large inputs of fertilizer, pesticides, and water Multiple cropping

  9. Second Green Revolution Mostly in tropical and subtropical developing countries Introduction of new fast growing, high-yield varieties of crops (wheat and rice) Need fertile soils and ample water

  10. Environmental Effects of Food Production

  11. Increasing food sources for an expanding population 1. GMO - Genetically modified organisms

  12. 2. Try new foods Winged bean

  13. Microlivestock 3. Irrigating more land 4. Cultivating more land 5. Grow more food in urban areas

  14. 6. Produce more meat Rangeland - uses native vegetation Pasture - uses domesticated or introduced forage plants Feedlots - grain, animal by-products

  15. Environmental problems with higher meat production Concentrates pollution problems Increased pressure on grain and fish supply Increased fossil fuel needs Increased spread of infectious livestock diseases

  16. 7. Catch and raise more fish

  17. Overfishing and habitat degradation (pg 304)

  18. Aquaculture - Fish farming and ranching

  19. Government and Agriculture policies (pg 307-309) Sustainable Agriculture Ch. 13-8
