1. What was the first agricultural revolution? When did it occur? What did humans do? How did it change the way humans lived? The First Agricultural Revolution was the transition of humans from nomadic hunting/gathering to sedentary agricultural production of domesticated plants and animals. It occured around 10,000 BC and 2000 BC, with the earliest known developments taking place in the Middle East. During the First Agricultural Revolution, Humans radically changed their behavior. During this period, humans began settling in to single areas and began cultivating the land, planting crops, and raising animals. The crops became domesticated as humans continued their use and animals became tame enough to be used for easy meat and pets/companions

Wheat is the first cereal to be cultivated by man. In several places in the Middle East it is being sowed, tended and reaped soon after 8000 BC

2. What was the second agricultural revolution?When did it occur? What changes happened in farming? The second agricultural revolution is generally said to have occurred along with the Industrial Revolution. The second agricultural revloution occurred from 1700 to 1900 in developed countries. The second revloution increased production and distribution of products fields were now doubled or tripled in size but still the same amount of labor. This increased in productivity and allowed population to increase on both a local and a global scale.

Scientists sometimes claim that, while carbon provides the quantity for life, nitrogen supplies its quality. Without nitrogen, there’d be no life. Nature makes amino acids, proteins, and nucleic acids from nitrogen; nitrogen is critical to the genetic information that structures life.

3.What was is the third agricultural revolution?When did it occur? What changes happened in farming? The Green Revolution was a period in time when new agricultural practices were created to help farmers all over the world. It was an international effort that was planned to eliminate hunger by improving crop performances, this rapid diffusion of more productive agriculture techniques occurred throughout the 1970s and the 1980s. his plan provided new practices that allowed farmers to produce more of the same product within the same amount of land. This meant that the farmers could get more out of their land than they used to

Modern agriculture is a term used to describe the wide type of production practices employed by American farmers

4.What are genetically modified organisms? How do they change farming? What are pros and cons of GMO's? A GMO (genetically modified organism) is the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. One of the major selling points was that these new crop varieties would reduce the use of pesticides after all, if the crop plant itself was producing a toxin that killed major insect pests. Pros: resistance to insects,tolerance to herbicides,tolerance for heat, cold, or drought,crop yield. Cons: Allergies, Antibiotic resistance, Cancer.
