1st Agricultural Revolution:

The first agricultural revolution happened around 10,000 years ago with a few women going around spreading seeds around their regular campsite. They, along with help from a few men, made sticks to dig into the ground and uproot the plants easily. Also they made spears to hunt game at longer distances. One of the more commonly used methods was the Slash-and-Burn. Farmers would cut down trees and grass then burn them along with their field and the leftover ash would fertilize the soil. These advances in their farm tools made it easier to harvest crops and hunt animals, it also made it more efficient and effective to work with these new tools.

Studies showed that corn was one of the first crops ever grown here in America. It was easily grown because of the worldwide rising temperatures, making the growing seasons longer and the land better for cultivation.

2nd Agricultural Revolution:

The second agricultural revolution happened between the late 1700's through to the late 1800's. Some new changes took place during this time period including the newly invented seed drill, a few poorly made tractors, fertilizers, crop rotations, Dutch plow, and threshing machines.

In the picture above, a farmer is using another version of a plow being pulled by mules. This invention by itself changed farming by just speeding up the process of tilling up a field getting it ready for the crop rotations, also for the fertilizers and seed drills. This also changed the soils state by making it more rich and nutritious with the fertilizers that were used.

3rd Agricultural Revolution:

The third agricultural revolution, also called the Green Revolution, was/is a worldwide revolution that worked to improve crop performances. The Green Revolution started in the 1960's through to about the 1980's. In those days farmers often used many different machines and newly made hybrid seeds. The newly made seeds changed the quality and quantity of the crops farmers made. It made it so they could plant better and more of one certain crop in a given area of their land. The Green Revolution also made higher yields, improved rice strains, had greater use of fertilizers, and greater use of irrigation. With the improvements with rice strains this made Asia's rice production grow at a rate of about 3.0% until the 1980's.

The definition of a 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, says the Institute for Responsible Technology. GMO's were introduced to crops to try and prevent or lower the use of pesticides, scientists thought that if they make a product that helps crops produce their own toxin that it would be better for the crop itself as well as minimize the workload of farmers.

GMO's

Pros: Tolerance to herbicides, resistance to insects, tolerance for heat; cold; drought, and crop yield. Cons: Allergic reactions, antibiotic resistance, and may cause some forms of cancer.

differences:

Subsistence farming is a style of farming in which the farmers focus on growing just enough food to feed themselves and their families.

Sustainable farming is a style at which farmers will produce foods, fibers, and other plants or animal products in farming practices to protect the environment.

Lastly, commercial farming is a style at which farmers grow crops and rear animals to sell them in markets for others needs.

These three styles of farming are different because of the way they benefit different people. Subsistence farming helps only the farmer's family, including him/herself, while commercial farming helps people in the community by selling its goods. Sustainable farming on the other hand helps the environment instead of helping just a specific group of people.

Fun Facts:

- Like snowflakes, no two cows have the same pattern of spots. - Pork is the widely most eaten meat in the U.S. - One pound of wool can make 10 miles of yarn. - The heaviest turkey ever raised was 86 pounds, about the average size of a third-grader.

Video:

The video will show a little extra about GMO's but you should get the general idea. :)
