Food Production
2
How is food produced? Industrial Agriculture Traditional Agriculture
6
Green Revolution Develop monocultures of high-yield key crops Large inputs of fertilizer, pesticides, and water Multiple cropping

17
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
19
Environmental Effects of Food Production
22
Increasing food sources for an expanding population 1. GMO - Genetically modified organisms
24
2. Try new foods Winged bean
25
Microlivestock 3. Irrigating more land 4. Cultivating more land 5. Grow more food in urban areas
26
6. Produce more meat Rangeland - uses native vegetation Pasture - uses domesticated or introduced forage plants Feedlots - grain, animal by-products
27
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
28
7. Catch and raise more fish
30
Overfishing and habitat degradation (pg 304)
31
Aquaculture - Fish farming and ranching
33
Government and Agriculture policies (pg 307-309) Sustainable Agriculture Ch. 13-8
