Agricultural Revolutions
A brief summary of module 8 in lieu of the DBA.
8.01 Agricultural Revolutions
Agriculture is the modification of Earth by humans to raise crops and animals for food or to sell. Agriculture was born out of hunting and gathering. As human populations began to experiment with growing plants and raising animals thousands of years ago, the concept of agriculture as it is known today was established. In this interactive, you will explore the development of agriculture, identify the hearths of plant and animal domestication, and learn about some of the agricultural products that emerged from each hearth.
The Columbian Exchange, which occurred during the 1500s, when Europeans began colonizing North and South America, agricultural products were exchanged between the Old World (Europe, Africa, and Asia) and the New World (North and South America).
Geographers often divide agriculture into two essential types: subsistence agriculture, or the production of plants and animals for survival, and commercial agriculture, or the production of plants and animals on a larger scale for sale.
The Second Agricultural Revolution, which marked the beginning of the shift from subsistence agriculture to commercial agriculture, began alongside the Industrial Revolution in the late 1700s. The period of industrial and technological growth that took place during the Industrial Revolution resulted in the development of new devices, such as the cotton gin and the mechanical reaper, that began to allow farm work to be done more quickly and efficiently.
During the 20th century, the Third Agricultural Revolution, also called the Green Revolution, again began to change how farmers practiced agriculture to form modern commercial farming. Farmers—often large corporations—may not only grow crops, but also process and sell them. Biotechnology, increased food processing, and more powerful machinery also characterized the Third Agricultural Revolution. This revolution helped transform the face of
