Types of Agriculture: Industrialized and Subsistence Agriculture

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.

Problems in Agriculture: Loss of Land and Decreased Varieties

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.

Land Degradation and Habitat Fragmentation: The Environmental Impacts of Industrialized Agriculture

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.
