What is the Green Revolution?
The was a period of significant development in agriculture that took place in the mid-20th century, primarily in developing countries. It was characterized by the introduction of high-yield varieties of crops, the use of and other technological innovations, and the application of and . The had a number of positive impacts, including increased food production, improved living standards, and . However, it also had negative impacts, including , the , and the . The is still controversial, with some people arguing that it has been beneficial and others arguing that its negative impacts have outweighed its benefits.
Where did it take place?
The took place primarily in countries in Latin America, Asia, and Africa, including Mexico, India, and Pakistan.
Why was it important?
The was important because it significantly increased and helped to feed the growing population in developing countries. Prior to the , many countries were facing food shortages and were unable to meet the needs of their populations.

(Genetic manipulation)
Genetically Modified Organisms (GMOs)
Genetically modified organisms (GMOs) are living organisms that have had their DNA altered in a way that does not occur naturally. This is typically done using genetic engineering techniques, which allow scientists to insert, delete, or modify specific genes in the organism's DNA. GMOs are used in a variety of applications, including medicine, agriculture, and research.
In agriculture, GMOs are used to produce crops that are resistant to pests, diseases, and herbicides, or that have other desirable traits, such as increased nutrient content or drought tolerance. Some of the crops that are commonly grown using GMOs include corn, soybeans, cotton, and canola.
The use of GMOs in agriculture has been the subject of much debate and controversy. Some people argue that GMOs have the potential to increase food production and reduce the need for chemical and herbicides, while others are concerned about the potential risks to human health and the environment.
