The Three Agricultural Revolution By: Jonny kovach

Today I am going to be talking about the three agricultural Revolutions. All of these revolutions have started somewhere and have expanded. The five agricultural hearths are Mesoamerica, Nile valley, Mesopotamia, Indus valley, and Huang He River Valley.

The first crop that was ever grown was wheat.(Left) The five agricultural hearths.(Right)

First Agricultural Revolution

The Agricultural Revolution Neolithic Revolution Domestication of plants and animals. This revolution started about 11,000 years ago. Humans started out as hunting and gathering of animals, fruits, and vegetables. As the humans started to grow knowledge of their surroundings they began to grow crops that would be way more sufficient. A very good example of this was corn. Humans began to make areas that they would use for growing crops called farming. This was a huge benefit for the humans because they didn't have to go out and look for all of their food, they could just get food from the farm. It also served as food that would always grow back as long as they keep watering and farming the crops.

Farming Equipment was a major change that happened and the picture with the red farming equipment (left). Over years and years farming equipment has evolved to be the most efficient.

Second Agricultural Revolution

The second Agricultural Revolution is mechanization of farming improved efficiency and it first started in Western Europe. It began in the 1700s to the 1900. It improved the efficiency of growing crops with equipment and it meant that farming could get bigger and have more food for the people. It was industrializing like many other companies were at that time. An example of the second Agricultural Revolution is crop rotation where they rotate the land used for crops and can harvest the crops while the other crops are growing. Another example is that the machinery was helping the demand the people had so they could keep up.

THe farming tractor is spraying farming chemicals for the crops to grow better for him to sell. Scientists work to keep improving the farming chemicals to get the best crops.

Third Agricultural Revolution

The third agricultural revolution is technological innovations and better ways to farm. Biotechnology is a very big part of the third revolution with scientists working hard to evolve the farming strategy. With the scientists making all of these improvements of growing crops includes GMO's. GMO's are genetically modified organisms and has changed the way humans farm. Farmers can make the crops grow way faster for the demand of food. Farmers can now make the vegetables more colorful to look more appealing.

Evolution of Food Transportation

How we get our food to other places has changed globally. Grocery stores can have fruit from countries across the world. Before there were planes and trucks that can keep food fresh for days people had to rely on their transportation and could only go around their area to gather food. In today's world we have trucks and airplanes that keep food cold and can get food that can grow in an area that is not suitable for food that can't be grown in other areas to the grocery store in your area.

The Evolution of Farming and GMO's

Farming has changed immensely over the years and years of growing crops. From hunting and gathering just to survive to growing crops to sell to the world. A very huge way that farming has changed is called GMO's. GMO;s are genetically modified organisms. They have many pros and cons because it is fairly new. The pros are resistant to insects, tolerance for heat, cold, and drought, and crop yield. The potential cons are allergies, antibiotic resistance, or cancer.
