The First Agriculture Revolution
The first agriculture revolution started around 11,000 BC, humans contributed to it by settling in the fertile crescent area in the middle east. They also began cultivating the land, planting crops, and raising animals. The crops later on became domesticated and the animals tame enough for easy meat/pet companions. This changed the way the humans lived by changing their behaviors completely. Many people believe that after the last ice age it had a huge impact on the shift of the first agriculture revolution, the areas where the revolution first cropped the areas where well irrigated and warm which made perfect farming conditions. The plants they would use as the crops were wild grasses that they would turn into domesticated grains (wheat,barley,rice,maize).
The Second Agriculture Revolution
The second agriculture revolution occured about a century ago. It coincided with the industrial revolution, it was composed of a series of innovations, improvements, and techniques. It had a major impact in western Europe, some of the major inventions that were made during this time were the plow, horse collar, and the seed drill. It involved a crop rotation and a four-course system.
The Third Agriculture Revolution
The Third Agriculture Revolution happened around the 1970's and 1980's. During this era there were quite a few technological innovations and scientific farming methods. Mechanization, chemical applications, and biotechnology was also begining to be used. They then began to use gas and diesel tractors. But because of these machines there were less laborers, but the amount have land used increased and so did the yields. Also there was a lot of pollution and reliance on petroleum. Then gmos were developed and used to help evolve the groups and the animals to.
