The first agricultural revolution is the transformation of human societies from hunting and gathering to farming. The first agricultural revolution was first starting in 10,000 BC and 2,000 BC. Humans were raising livestock and planting crops. For a lot of years the dominant structure of human life had been small nomadic bands. Now humans would live in fixed locations that ranged from villages and cities.
The humans back then did not have the best crops but there were crops that helped them survive
The second agricultural revolution is has to do with the industrial revolution. It was a revolution that would move agriculture beyond subsistence to generate the kinds of surpluses needed to feed thousands of people working in factories instead of in agricultural fields. By the 17th and 18th century corn and potatoes are introduced. When they're are more crops than the humans that have been living back then then they can survive with more food.
The third agricultural revolution was created to help the farmers all around the world. It also helped to create crops and make it easier for farmers. The revolution started in the 1970's and 1980's and it's still going on today. The third agricultural revolution is also known as the green revolution. The Green Revolution allowed scientists to create higher-yield hybrids that are adapted to environmental conditions in specific regions.
