The Green Revolution introduced new methods for growing, harvesting, and processing crops. It brought modern machines and other technology to farming. As a result, farmers were able to produce more and better food.
Farmers in Mexico, India, Kenya, and many other countries began to grow new plant varieties created by scientists. They got larger crops as a result. Farmers also learned how to treat their crops with pesticides and fertilizers. These chemicals protected the plants from insect pests, weeds, and disease. Complex systems of irrigation, or watering, also came into use. New machinery for plowing the soil and harvesting crops made farm work easier to do.
Farmers still use the methods of the Green Revolution. One positive result of the movement was that many poor countries became able to grow enough food to feed their own people. This lowered the risk of famine, or a severe shortage of food.
However, the Green Revolution was not a complete success. As time went on, some of the new types of seeds produced less food than they did at first. Many of the pesticides and fertilizers were harmful to humans and polluted the land and water. Also, farmers using the new seeds had to buy them from other countries instead of using seeds from their own land. Finally, even though the Green Revolution produced more food, that food did not always reach the people who needed it.
