Three Agricultural Revolutions Arianna Grotheer

The First Agricultural Revolution occurred between 10,000 BC and 2,000 BC. During this revolution humans learned to domesticate crops and livestock, which took them away from their lifestyle of following the paths of the animals to get food. They began settling down and farming crops and livestock. Different regions around the world grew different plants and cared for different animals.

The Second Agricultural Revolution occurred from 1700 to 1900. During this time many changes and advances happened for farmers all over the world. People began using animals and inventing machines to help decrease the work amount while farming. Farmers began using machines like plows, and they used animals to pull them. While this decreased the time it took to plant, it also put a lot of people out of work.

The Third Agricultural Revolution, or the Green Revolution, began in the 1940's and is still happening today. Scientists began genetically modifying crops to make them bigger and increase nutrient levels. Today we use machines to harvest crops which makes the job quicker and easier.

A genetically modified organism (GMO) is when a gene from one organism is moved to change or improve another organism. Farming has changed because the crops farmers are harvesting bigger crops, but the chemicals in those crops can cause serious harm.
