About This Chapter
Food Production & Sustainability - Chapter Summary
The lessons in this chapter provide an overview of food production and sustainability. You'll find an informative discussion of key topics such as genetically modified food and agricultural societies. After completing the chapter, you should be positioned to:
- Define food insecurity, and analyze the impact and prevention efforts
- Discuss problems in agriculture, such as loss of land and decreased varieties
- Explain industrialized and subsistence agriculture
- Explore the history and distinguishing features of agricultural societies
- Assess the benefits of sustainable agriculture
- Examine fishing techniques and their effects on ecosystems
- Understand microbial processes and products in biotechnology
- Discuss genetically modified food
These video lessons are brief and engaging, which helps you to easily understand the information presented. Our expert instructors are effective and use plenty of examples. The video timelines allow you to navigate the videos and focus on topics that are of foremost interest to you. Each lesson is accompanied by a brief multiple-choice quiz to test your knowledge. Full video transcripts are also available.
1. 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.
2. 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.
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. Agricultural Societies: Definition, History & Distinguishing Features
This lesson will seek to define intensive agriculture. In doing so, it will highlight the concepts of subsistence versus commercialization. It will also define cash crops and agribusinesses.
5. 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.
6. Fishing Techniques & Their Effects on Ecosystems
Certain fishing techniques are used because they are very efficient. However, many of these techniques are also very destructive to ecosystems and the physical environment. In this lesson, you'll learn about some of these techniques and how they affect the ecosystems they are used in.
7. Microbial Processes & Products in Biotechnology
Biotechnology may sound like a fancy term, but it is applicable to very basic things in your everyday life. In this video lesson we'll look at some of the things that come from microbes in biotechnology, some of which might surprise you!
8. What is Genetically Modified Food?
In this lesson, we will explore a recent advancement in agriculture known as genetic engineering. We'll look at how it's used to create genetically modified foods and also examine the advantages and disadvantages of these types of foods.
