What was the first agricultural revolution?
It occurred worldwide between 10,000 BC and 2000 BC, with the earliest known developments taking place in the Middle East.Farming and the raising of livestock tied people to land for cultivation and grazing grounds, and this transition gave rise to permanent settlements. For tens of thousands of years, the dominant structure of human life had been small nomadic bands. From this point on, most humans would live in fixed locations that ranged from villages to cities. This settlement, in turn, led to the development of job specialization, complex political structures, non-portable possessions, architecture, and the rise of industry and commerce.
First crop grown by humans was wild grain/wheat.
What was the second agricultural revolution?
It happened in the late 1700s - late 1800s. The second agricultural revolution occurred to increase food production and allow for farmers to move to urban areas for factory work. There was also more framing machines in this revolution.
What was(is) the third agricultural revolution?
There was more advanced technology used for farming and to increase farming yields and/or outputs from the same amount of land with efficient use of land. Development of genetically engineered crops (GE) or genetically modified organisms (GMOs) started happening as well.
What are genetically modified organisms?
Because GMOs are novel life forms, biotechnology companies have been able to obtain patents with which to restrict their use. As a result, the companies that make GMOs now have the power to sue farmers whose fields are contaminated with GMOs, even when it is the result of inevitable drift from neighboring fields.
Pros and cons of gmoś
Pros-resistance to insects, tolerance to herbicides, tolerance for heat, cold, or drought, and crop yield
Potential cons are allergies, Antibiotic resistance, and cancer.
