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.
13. What is Caffeine? - Structure & Side Effects
Caffeine is one of the most commonly used drugs in the world, but what is it? Found in coffee, tea, soda, some medications, and energy drinks, the positive and negative side effects of caffeine use are important to understand. This lesson describes the chemical composition and side effects of caffeine.
14. What is IgD? - Definition & Function
This lesson will provide a quick review of antibodies. Then you will discover what IgD means, what it is, and where it comes from. You will also learn what is known about its role in the body.
15. Genetic Engineering in Animals
In this lesson, we will explore genetic engineering and genetically modified organisms. We will learn what types of animals are genetically engineered and why it is done.
16. Why Does Swiss Cheese Have Holes?
In this lesson we will learn a little bit about the process of cheesemaking. We will discuss the three types of bacteria common to Swiss cheese, and how bacteria contribute to the holes in Swiss cheese.
17. Marmalade: Etymology, History & Facts
How much do you know about marmalade? This lesson explores the naming of marmalade, its history, and facts about this jelly-like food. You'll leave an expert, and may even want some marmalade for your toast.
18. Bromatology: Definition & Facts
After reading this lesson, you'll learn what a bromatologist is, and what one does. You'll also see just how important such a position is when it comes to the health of food businesses and consumers alike.
