The 1st Agriculture Revolution
Neolithic Revolution: It took place in 8,000 BCE and humans discovered how to farm. It changed how they lived by how food sources became more reliable, being able to store food, and being able to settle down and establish permanent settlements near their food.
The 2nd Agricultural Revolution
Industrial Revolution: It started in the 1600s in Western Europe and spread by 1800s to North America. Technological changes happened and began new methods: Crop rotation, and better horse collars. Later innovations replaced human labor with machines, supplement natural fertilizers, and pesticides with chemicals.
The 3rd Agricultural Revolution
Green Revolution: The Green Revolution started in the 1940's and 1950's. New strains of hybrid seeds and fertilizers were invented and dramatically increased crop output. Scientists found new hybrid strains of wheat, maize, and rice that were higher yielding, capable of producing more food at a faster pace.
Genetically Modified Organisms(GMO's)
GMO'S are genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. GMO's changed farming by reducing the use of pesticides. The Pros of GMO's are that if they generate healthier crops it will lower the risk of crop failure and make crops more resistant to extreme weather. The Cons of GMO's are that food allergies in children under 18 spiked 3.4 percent in 1998 to 5.1 percent in 2010.
Subsistence, Sustainable, and Commercial Farming.
Subsistence Farming is when people grow enough crops to survive. Sustainable Farming is the production of food that uses farming techniques that protects the environment. Commercial Farming is When people farm to make money.
