Green Revolution represents a set of technological innovations that aim to improve agricultural practices.

The first country to apply the concept was Mexico and its use spread to several countries, which significantly increased their food production.

The Green Revolution started after World War II (1939-1945) when hunger was a real problem in countries in sub-Saharan Africa and southern Asia.

The Revolution consisted of using the best technology to produce more food on the same land. In this way, if they developed seeds of genetically modified plants that produced more, had better response to fertilizers and greater resistance to pests.

In addition, it was tried to apply the modern management methods of the factories to the field. To this end, research began on how best to equalize the limitations of the land, such as lack of irrigation, greater performance of agricultural implements such as planters and harvesters.

All of these actions were already used by farmers throughout human history. However, they are now typical of an industrial and capitalist society.
