1 Hazards of Industrial Agriculture
Key: AWL to Study, Low-frequency Vocabulary What are the hazards of industrial agriculture?

2 Organic Farming: A Growing Trend
Consumer demand for organic farming is rising at 20% per year. The highest growth is in Argentina, US, and China. People are growing conscious of adverse effects of industrial agriculture, where there is a focus on maximizing profits at the expense of health and the environment. How do you think industrial agriculture contributes to global warming and water pollution?

3 Health Risks: Industrial Methods
Pesticide residues on produce remain after washing and peeling. have links to cancer. Antibiotics we ingest from plant and animal sources lead to the development of untreatable superbugs Do you worry about pesticide residues on or antibiotics in your food? Explain.

4 Additional Health Risks
Plant and animal growth hormones disrupt endocrine system. lead to early puberty. Biological engineering Unregulated items are virtually invisible in stores. Manipulation of genetic code could impact health. How do you think genetically modified food might impact your health?

5 Environmental Hazards
Environmental hazards comprise air pollution, global warming, and other problems. Synthetic fertilizers largest source of nitrous oxide emissions 300 times more toxic than carbon dioxide gases will affect air pollution and intensify global warming if continued Are you concerned about air pollution in your country? Why or why not?

6 Authorities on Water Pollution
Animal waste, fertilizers, and pesticides leach into soil. They run off through irrigation and contaminate ground water (large portion of water supply). They contain nitrates, which cause permanent damage to ground water. Are you concerned about water pollution in your country? Why or why not?

7 Dead Zones in Oceans Preponderance of nitrogen in fertilizers
helps crops grow; harms oceans generates algal overgrowth Algal overgrowth depletes oxygen in water no plant or animal can survive

8 Unsustainable Soil Industrial mono-cropping: one crop is planted repeatedly on a single field. The process relies on the use of synthetic fertilizers. Mono-cropping kills microorganisms needed to produce soil nutrients. Infertile soil leads to erosion, unsustainable farmlands, and reduced biodiversity. If mono-cropping is destroying farmlands and biodiversity, what is the alternative?

9 Vicious Cycle Soil infertility leads to a vicious cycle
of fertilizer use. Increasing fertilizer use leads to environmental hazards. Increased use of pesticides Only the fittest pests survive. Stronger pesticides are then needed. What are the environmental hazards associated with the use of pesticides?

10 What are the advantages of eating organic food?
Organic Farming Organic farming prohibits the use of synthetic fertilizers and pesticides, hormones, antibiotics, and genetically modified organisms. It ensures soil sustainability and overall quality. What are the advantages of eating organic food?

11 How does organic farming affect soil?
Crop Rotation Holistic farming techniques infuse soil with essential nutrients. ensure different crops are planted every year. vary the nutrient demand in soil. create sustainable soil. How does organic farming affect soil?

12 Animal Welfare Small-scale organic farms are Free-range farms
less likely to confine livestock to small spaces. against the use of antibiotics. Free-range farms allow animals to roam freely. reduce stress and susceptibility to disease. How do you feel about confining animals to small spaces in order to produce food?
