What was the first agricultural revolution? The First Agricultural Revolution was the change of human societies from hunting and gathering to farming. The change started worldwide between 10,000 BC and 2000 BC, the developments started taking place in the Middle East.When did it occur? What did humans do? How did it change the way humans lived?The farmers began to breed wild grasses into domesticated grains (wheat, barley, rice, maize, etc.) and to bring dogs, cattle, sheep, goats, pigs, horses, and poultry under their control. In human societies possessing domestic animals, livestock fed more people by furnishing meat, milk, and fertilizer and offered more strength for agricultural techniques like pulling plows. But, although this domestication of animals was in many ways the greatest advancement for thousands of years, it also unleashed a new danger: infectious disease. Pathogens which had once been exclusive to animals transferred to humans, with these animal diseases leaping the species gap and mutating into human diseases. This transmutation of disease is still apparent, as it is believed that humans nowadays share more than sixty micro-organic diseases with dogs, and only slightly fewer with cattle, sheep, goats, pigs, and poultry.Permanent settlements afforded golden opportunities for insects, vermin and parasites. Settlement also increased malaria, as farmland created the warm water-holes and furrows which make perfect breeding environments for mosquitoes.

What was the second agricultural revolution?The second agricultural revolution is generally said to have occurred along with the Industrial Revolution. It came about in part because of the Industrial Revolution and it helped allow the Industrial Revolution to happen. The second agricultural revolution was based on a greater use of technology.

When did it occur? What changes happened in farming?There was no single factor, or combination of factors, that led people to take up farming in different parts of the world. In the Near East, for example, it’s thought that climatic changes at the end of the last ice age brought seasonal conditions that favored annual plants like wild cereals. Elsewhere, such as in East Asia, increased pressure on natural food resources may have forced people to find homegrown solutions. But whatever the reasons for its independent origins, farming sowed the seeds for the modern age.

What was(is) the third agricultural revolution?biotechnology is the third. Mechanization began replacing animal and human labor in the United States during the late nineteenth century.

When did it occur? What changes happened in farming?The Third Agricultural Revolution (also called the Green Revolution): The Green Revolution was a period in time when new agricultural practices were created to help farmers all over the world. It was an international effort that was planned to eliminate hunger by improving crop performances. This plan provided new practices that allowed farmers to produce more of the same product within the same amount of land.This rapid diffusion of more productive agriculture techniques occurred throughout the 1970s and the 1980s. The plan had two main practices: the introduction of newer higher-yield seeds and the expanded use of fertilizers. The Green Revolution answered questions from experts about massive global famine.

The Green Revolution has strong cases on why it is a success and a failure. The Green Revolution allowed scientists to create higher-yield hybrids that are adapted to environmental conditions in specific regions. This allowed scientists to predict the maximum annual crop yield in Asia and Latin America, which was about 6,000 kilograms per hectare. The Green Revolution was largely responsible for preventing a food crisis in these regions during the 1970s and 1980s. But the Green Revolution has not proven itself to be a successful strategy in ending world hunger. The question of famine is not that we need more food, but how we distribute it within the world. The Green Revolution does not alter the distribution of economic power—more specifically purchasing land and purchasing power.

What are genetically modified organisms? How do they change farming? What are pros and cons of GMOs? 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.genetically modified organisms (GMOs) has rippled through the fields and homesteads of the United States, changing the way farmers conduct their operation. Fueling both the industrialization of agriculture as well as an organic food response, GMOs have pushed the culture of farming in new directions.Pros of GM foods: resistance to insects,tolerance to herbicides,tolerance for heat, cold, or drought,crop yield.Cons of GM foods:Allergies,Antibiotic resistance,Cancer,
