date when it occurred- between 10,000 BC and 2000 BC
what the humans did- The group that started the First Agricultural Revolution were the early members of humanity that settled in the Fertile Crescent area of the Middle East. Other groups achieved similar results later in China (unknown if independent from Fertile Crescent) and South America. The members of this group were the first to settle into a specific area of land and stay sedentary for long periods of time.
how it changed how humans lived- During the First Agricultural Revolution, Humans radically changed their behavior. During this period, humans began settling in to single areas and began cultivating the land, planting crops, and raising animals. The crops became domesticated as humans continued their use and animals became tame enough to be used for easy meat and pets/companions. The earliest examples of this behavior appeared in fertile areas around rivers primarily.
^wheat was the first crop grown by humans
the second agriculture revolution- agricultural benefited from the Industrial revolution.
date it occurred- from 1700 to 1900.
changes in farming- Helped to improve food production to feed more than just the farmer and a village. New fertilizer and artificial feed is introduced. Planting in rows is becoming common because it is easier to manage and harvest
third agriculture revolution- called the green revolution. Period in time when new agricultural practices were created to help farmers over the world.
date it occurred- throughout the 1970s and the 1980s.
changes in farming- New advances with crops allowing further production, better performance, and land efficiency.
GMO is- the result of a laboratory process where genes from the DNA of one species are extracted and artificially forced into the genes of an unrelated plant or animal. The foreign genes may come from bacteria, viruses, insects, animals or even humans.
how GMO changed farming- Genetically modified (GM) crops have been rapidly adopted by the American farmer. Transgenic traits in corn and soybeans conferring the ability to resist the herbicide glyphosate are an omnipresent variety found in fields today.
pros of GMO- resistance to insects. tolerance to herbicides. tolerance for heat, cold, or drought.
cons of GMO- They contribute to environmental damage. They create gene migration. They can result to lowered resistance to antibiotics.
Explain the difference between subsistence, sustainable, and commercial farming
difference between subsistence, sustainable, and commercial farming- Commercial farming is typically done on a very large scale, often by agricultural corporations. subsistence farming, farmers grow a wider range of crops based on the anticipated needs of their families or communities. Traditionally, subsistence farmers have eaten what they grow. sustainable agriculture is the production of food, fiber, or other plant or animal products using farming techniques that protect the environment, public health, human communities, and animal welfare.
4 facts- Fruit farming began sometime between 6000 and 3000 B.C. Figs were one of the first cultivated fruit crops. - bananas are the number 1 fruit crop in the world. - Farmers often plant tall, dense trees on the edges of fruit farms. These trees provide a windbreak, which helps prevent soil erosion. - Bees contribute to more than $15 billion worth of crops every year through pollination.
