Neolithic Revolution: This was the first ever agricultural revolution that occurred in 8000 BCE. During this revolution people discovered how to farm. This helped them because it allowed them to settle near food, they were able to store food, and they had reliable food sources. The first crops people grew were small and the growing of grain helped support a small population.
Industrial Revolution: The second agricultural revolution was known as the industrial revolution and it occurred in the 18th and 19th centuries. People built machinery to help with their farming and production. It increased manufactured goods and improved the standard of living for some people. People grew larger crops because they had more technology to help harvest and plant.
Green Revolution: The Green Revolution was the time of the fertilizer and it started in the 1950's to 1960's. During this revolution the amount of calories produced per acre increased. Irrigation also helped allow more crops to be grown in various areas.
Genetically Modified Organisms: Genetically modified organisms, or GMO's, are when scientist extract genes from one species and put them into another one. GMO's now don't allow certain crops to die if you use the wrong fertilizer and it is bad for some people. Some people think that GMO's are harmful because they can cause environmental damage and can cause health problems for consumers. Others think that GMOs can be good because they reduce pesticide useage.
Subsistence, Commercial, and Sustainable: Subsistence farming is when people farm for only their family, not to sell to other consumers. Commercial farming is when people grow crops to sell to people. sustainable farming is using farming techniques that are healthier for consumers and better for the environment.
Facts: One fact about agriculture is that 40% of the population works in the agriculture field. It also takes more labor for organic farming but it brings in lots more profit. In 2011, 88% of corn and 94% of soybeans were genetically modified. Farming gives jobs to 24 million American worker which is equivalent to 17% of the workforce.
