The agricultural revolutions

The first agricultural revolution

The first agricultural revolution, also known as neolithic revolution, was the transition from people hunting and gathering for food, to domesticating plants and animals. It started around 10000 B.C. , when people began to cultivate plants and animals that lived naturally in their areas. For example south east asia cultivated rice, corn was cultivated in mexico, potatoes in the andes, wheat in the fertile crescent, and yams in west africa. This transition allowed people to settle down, build the first civilisations, and towns, instead of moving with the seasons to follow the growing patterns of plants and the migration of the animals they hunted. It also meant a continuous food supply that could support traders who helped create economies and a large population of people in case of drought or famine.

The first crops cultivated by man corn, rice, potatoes, yams, and wheat.
The second agricultural revolution

The second agricultural revolution was the industrialization of agriculture. It occurred alongside the industrial revolution. During this time period humans began to use the technological advances of the industrial revolution to create inventions such as the horse plow, the seed drill, and steam powered trains to transport food. All of which made food production, and food transportation easier.

The third agricultural revolution

The 3rd agricultural revolution began shortly after WW2. The third agricultural revolution was the applications of technological innovations, and scientific farming methods in agriculture. Today farming involves mechanized farm tools (Like combines and tractors), chemical use (Like pesticides, and Biotechnology. The 3rd agricultural revolution also reduced the number of laborers, increased the amount of land used in farming, and increased crop yields.

genetically modified organisms

GMOs are plants and animals genetically modified as a result of biotechnology. They changed farming because they could be genetically modified to grow faster, larger, and can be made resistant to specific pesticides. All of this allows for a greater crop yield. The pros of GMO's are that they are more resistant to weeds, pest, and diseases. They also sometimes have higher nutritional values. The disadvantages of GMOs are that some are are made from mixing genes of different plants and animals, they are sometimes marketed without labeling, and the long term consequences of consuming them are not understood yet.
