A village planting and harvesting crops also building shelters
The first agricultural revolution was the change in human behaviors. Going from hunter/gatherers to production of crops and domestication of animals. The revolution started somewhere around 11,000 BC. The exact point it started is uncertain because little was recorded during that time. During this revolution humans changed their behavior and started settling into homes they have built, planting crops, and taking care of animals. It really changed how humans lived, because without the revolution we wouldn't have the technology and behavior we have today.
Machinery used to harvest crops
The second agricultural revolution and the industrial revolution go hand in hand. The second agricultural revolution was humans improving the way they grow and produce food. The revolution occurred from 1700 to 1900 in developed countries. Farmers started using machinery the plant and harvest their crops more efficiently.
Genetic engineering is used to make larger portions of food
The third agricultural revolution or also known as the green revolution was invention of high-yield grains with the goal of reducing hunger. The revolution started in the later half of the 20th century and is still continuing today. Farmers started using GMOs or genetically modified organisms to increase growth of crops.
Genetically modified organisms or GMOs are hybridization and crossbreeding with crops. GMOs change farming by a lot. Farmers fields contaminated with GMOs can spread so other farmers land is contaminated with GMOs. Pros to having GMOs are resistance to insects, tolerance to herbicides, heat cold and drought, and crop yield. The cons of having GMOs are allergies, antibiotic resistance, and cancer.
There are differences between commercial, sustainable, subsistence farming. Commercial farming is when you sell and make a profit off of the food you produce. Sustainable farming is when you produce food healthy for the environment or GMO free. Subsistence farming is when you produce enough food to feed yourself and your family.
- Four fun facts on agriculture
- 1. 31% of U.S. gross farm income comes directly from export
- 2. today’s farmers produce 262 percent more food with 2 percent fewer inputs (labor, seeds, feed, fertilizer, etc.), compared with 1950.
- 3. 2.2 million farms dot America’s rural landscape. About 97 percent of U.S. farms are operated by families – individuals, family partnerships or family corporations.
- 4. Farm and ranch families comprise just 2 percent of the U.S. population.
