Agriculture By Sydney Ninke

First Agricultural Revolution: The Neolithic Revolution

Wheat, first crop grown

Wheat was the very first crop ever to be domesticated and grown by humans.

The First Agricultural Revolution happened around 15 - 20 thousand years ago. A worldwide transition from hunting and gathering to domestication of plants and animals. This helped people to settle and build civilization, instead of moving all the time like you would with hunting and gathering. People also came up with slash and burn, existing vegetation is cut down and burned off before new seeds are grown. This causes a lot of problems to the environment. Most of their way of farming was hurtful to the environment. Without the First Agricultural Revolution we would not be in the technological advance that we are in today.

Seed Drill

The picture above is a photo of a seed drill invented in 1701, used in the 1700s around the industrial age. This a machine invented to plant seeds in even, straight rows, and pulled by a horse. Farmers had to throw the seed by hand, but this makes it easier to plant seeds.

The Second Agricultural Revolution occurred between the 1700s and 1900s. In this revolution, instead of farmers farming by hand they had machines that would help make farming easier for the farmers. It helped create jobs and increased food production, providing more food for families. The machines also helped make food transportation easier.

Also known as the Green Revolution

The Third Agricultural Revolution began around 1970s and 1980s, and is present now. Scientists discovered a way that its food's DNA contains one or more genes not normally found there. This is most likely to make food larger in order to feed more people. The new chemical fertilizers were created to make it possible to supply crops with extra nutrients. The High-yield crops are crops that are specifically designed to produce more overall yield. A method known as multiple cropping was also part of the Green Revolution and increased productivity. This created much more food for developing countries that were starving. In which Norman saved many lives for creating more food production.

Genetically Modified Organisms

Genetic modification is when you force genes from one species into another entirely unrelated species. It makes it possible to create fertilizers that kill bacteria, disease, and give extra nutrients to food. Also to make food larger and maybe even taste better. GMO's have cons too, they have helped the population of the world to be way overpopulated. Also it dramatically influenced the environment by increasing pollution and erosion and GMO's have not been fully tested on human safety.
