About This Chapter
Food and Agricultural Resources - Chapter Summary and Learning Objectives
Food. Some of us have a love/hate relationship with it because we are trying to lose weight. Others enjoy it to its fullest, indulging in every rich dish they can. Then there are those who struggle to get enough to eat every day. There are parts of the world where hunger is a very real problem. As you will learn in this chapter, there are a lot of difficult situations where growing the needed amount of food is tricky. These lessons will talk about malnutrition, types of agriculture and food insecurity. You will learn what challenges are faced when trying to feed a nation. Some of the other things you'll learn include:
- Recent trends in U.S. agriculture
- Aspects of industrialized agriculture
- The green revolution
- Endangered ecosystems
- Sustainable agriculture
- Pesticide use

1. Malnutrition: Causes of Over-nutrition and Under-nutrition & Most Affected Regions
Have you ever thought about your diet and whether or not you are getting the appropriate nutrients you need to remain healthy? In this lesson, we will describe the concept of malnutrition and explore the ways that people's diets can be unbalanced. We will also discuss regions of the world where malnutrition is prevalent and why.
2. What Is Food Insecurity? - Definition, Impact & Prevention Efforts
Although every human on Earth has to eat to survive, the amount of food consumed varies a great deal by region. In this lesson, we will explore the concept of food insecurity and the issues that are causing it. We will also discuss prevention methods in place to try to combat food insecurity.
3. Types of Agriculture: Industrialized and Subsistence Agriculture
In recent history, agriculture has been the main source of the food we consume on a daily basis. In this lesson, we will explore the difference between industrialized and subsistence agriculture. We will also investigate the different kinds of subsistence agriculture that are practiced.
4. Problems in Agriculture: Loss of Land and Decreased Varieties
Although we all currently rely on industrial agriculture to produce the majority of the food we eat, this type of agriculture is facing problems that may threaten its future. In this lesson, we will explore these problems and how they influence the future of food production.
5. Land Degradation and Habitat Fragmentation: The Environmental Impacts of Industrialized Agriculture
Although we all need food to survive, the methods we use to produce that food can be problematic. In this lesson, we will explore how industrialized agriculture negatively impacts the environment and, as a result, makes the land less productive in producing crops and livestock.
6. What Is the Green Revolution? - Definition, Benefits, and Issues
Over the years many significant agricultural changes have occurred in order to supply enough food for the growing human population. In this lesson, we will explore the Green Revolution and investigate the benefits and issues associated with this period.
7. Land Conservation: Criteria For Evaluation of Land and Most Endangered Lands in the US
Land is a very valuable thing and is used for many different purposes. We will explore why land should be conserved and the criteria for evaluating land. We will also identify some of the most endangered ecosystems in the United States.
8. What Is Sustainable Agriculture? - Definition, Benefits and Issues
The word 'sustainable' has become very popular these days and is used to describe many different things. In this lesson we will explore how sustainability is associated with agriculture and the benefits and issues of this type of farming.
9. What is Genetic Engineering? - Definition, Benefits & Issues
When most people think of genetics, they think of their own genes, but genetics is also very important in agriculture. In this lesson, we will explore genetic engineering and how it relates to agriculture. We will also investigate the benefits and issues associated with genetic engineering.
10. What Are Pesticides? - Definition and Difference Between Narrow-Spectrum & Broad-Spectrum
The crops and livestock we use for food are constantly at risk of harm from pests. This lesson will explore the methods for managing agricultural pests, including both narrow- and broad-spectrum pesticides.
11. Use of Pesticides: Benefits and Problems Associated with Pesticides
Pesticides are used worldwide to manage agricultural pests. They kill and repel unwanted pests, but also cause many human deaths each year. This lesson explores the widespread use of pesticides in agriculture and compares the benefits and problems associated with these helpful but dangerous chemicals.
12. Alternative Pest Control Methods for Agricultural Use
There is a move to reduce the use of pesticides in favor of more environmentally friendly methods of pest control. In this lesson, we'll explore alternative pest control methods, including how they work and the benefits and issues associated with each method.
