The Three Agricultural Revolutions By Lexi Rademacher

The First Agricultural Revolution-

  • The first agricultural revolution was the transition of humans from hunting/gathering to the production of domesticated plants and animals.
  • The group that started the First Agricultural Revolution were the early members of humanity that settled in the Middle East. The members of this group were the first to settle into a specific area of land and stay for long periods of time.

The First Agricultural Revolution Continued...

  • This transition occurred worldwide between 10,000 BC and 2000 BC
  • From this point on, most humans would live in fixed locations that ranged from villages to cities.
  • People can now grow an abundance of food in one place.
Cereal (older wheat crops) and barley were the first grown crops.

The second Agricultural Revolution

  • The second agricultural revolution coincided with the Industrial Revolution. Technology provided by the Industrial Revolution increased the production and distribution of products.
  • The 2 revolutions occurred from 1700 to 1900 in developed countries.
  • fields were now doubled or tripled in size
  • Mechanization increased in productivity and allowed population to increase
Less labor is being put into farming with the increase of technology .

The Third Agricultural Revolution

-Bio technology (Changing and organism's genetics.)

Technological innovations and scientific farming methods

this increased the process in producing crops and allowed population to increase.

Starting in the 1900's and currently in progress, the Third Agricultural Revolution developed Genetically Modified Organisms (GMO's)

Scientists are now able to change the DNA of plants like this seedless watermelon or seedless grapes.

Genetically Modified Organisms

GMO's are used for increased milk and egg production and higher meat proportions.

GMO's modify crops to grow at a faster rate to increase food production.

Pros: Genetically modified foods have stronger colors, an increase shelf life, eliminates seeds and can also provide nutritional benefits.

Cons: GMO's can cause allergic reactions and cause the effectiveness of antibiotics to work against illnesses.

GMO's making tomatoes grow bigger for consumer's wants.
