Chapter 12: Food Production and the Environment
|
Section 1: What is Food Security and Why is it Difficult to Attain?
Concept 12-1A: Many people in less-developed countries have health problems from not getting enough food, while many people in more-developed countries suffer health problems from eating too much. Concept 12-1B: The greatest obstacle to providing enough food for everyone are poverty, war, bad weather, climate change, and the harmful environmental effects of industrialized food production. Section 2: How is Food Produced?
Concept 12-2: We have used high-input industrialized agriculture and lower-input traditional agriculture to greatly increase food supplies. Section 3: What Environmental Problems Arise from Industrialized Food Production?
Concept 12-3: Future food production may be limited by soil erosion and degradation, desertification, irrigation water shortages, air and water pollution, climate change, and loss of biodiversity. |
Section 4: How Can We Protect Crops from Pests More Sustainably?
Concept 12-4: We can sharply cut pesticide use without decreasing crop yields by using a mix of cultivation techniques, biological pest controls, and small amounts of selected chemical pesticides as a last resort (integrated pest management). Section 5: How Can We Improve Food Security?
Concept 12-5: We can improve food security by reducing poverty and chronic malnutrition, relying more on locally grown food, and cutting food waste. Section 6: How Can We Produce Food More Sustainably?
Concept 12-6: We can produce food more sustainably by using resources more efficiently, sharply decreasing the harmful environmental effects of industrialized food production, and eliminating government subsidies that promote such harmful impacts. |
