First Agriculture Revolution
Neolithic Revolution: Happened around 8000 BCE. This is when people discovered how to farm. It changed the way people lived because they were able to store their food and they could settle down and establish settlements near their food. Wheat, Barley, Lentil, and Olive were the first crops grown.
Second Agriculture Revolution
Industrial Revolution: Started in the 1600's in western Europe. Technological changes and new methods (crop rotations and better horse collars) changed the way farming was done. This is when people started using machines instead of human labor.
Third Agriculture Revolution
Green Revolution: Began in the 1940's and 50's. In this point in time we came up with Biotechnology, new fertilizers, pesticides, herbicides, mechanization (tractors & combines), and irrigation so we don't have to rely on rain.
GMO stands for genetically modified organisms, and they are when a crop gets injected with genes from another organism to make the crop more resistant to different things. Some pros of GMO'S is that they are more resistant to insects and gathering healthier crops. Some cons are that they can pose a health risk in humans and pollen from modified plants can infect other plants creating superweeds.
