Agricultural Revolutions Jaylynn hovanetz

The First Agricultural Revolution;Neolithic Revolution

The first agricultural revolution was the domestication of plants and animals about 11,000 years ago. This was when humans turned away from hunting and gathering and went to farming and raising livestock which gave rise to permanent settlements. This made humans live in specific places like villages and cities.

One of the first crops grown was wheat.

The Second Agricultural Revolution

The second agricultural revolution came about around the same time as the industrial revolution which helped improve technological advances in producing the product and distributing it. It occurred in Western Europe. Many advancements in farming were made such as the plow, horse collar and seed drill.

The second agricultural revolution introduced crop rotation. Crop rotation was putting different crops in the same spot and rotating them one after another. This avoided depleting soil and helped avoid weeds and diseases.

The Third Agricultural Revolution; The Green Revolution

The third agricultural revolution occurred in the late 20th century and is still occurring today. The start to the third agricultural revolution was a result of how well the second agricultural revolution worked. It was corresponding with rapid population growth around the world and started because of the great success with the second agricultural revolution and the ability for a country to feed itself.

In the third agricultural revolution there were many technological innovations, biotechnology and mechanization, gas and diesel engine tractors, decrease in labor because of farming machines, and people had much more land.

Genetically Modified Organisms (GMO'S)

GMO's are plants and animals that are changed as a result of biotechnology. GMO's came about from DNA of one thing being put in another thing to make it "better". GMO's change farming By reducing the amount of pesticides. Some advantages of GMO's are that they are resistant to weeds, pests and diseases, and have a higher nutritional value. Some disadvantages are that it's mixing genes from different organisms, they are marketed without labeling, and they have long term consequences.

There are ways that you can determine if your produce is a GMO or not. (shown in the image above).
