USA HISTORY

Detailed explanation-1: -First and foremost is the change from nomadic to sedentary life. A sedentary society is one that doesn’t move around and is permanently settled in one place. When early humans began farming, they were able to produce enough food that they no longer had to migrate to their food source.

Detailed explanation-2: -Agricultural communities developed approximately 10, 000 years ago when humans began to domesticate plants and animals. By establishing domesticity, families and larger groups were able to build communities and transition from a nomadic hunter-gatherer lifestyle dependent on foraging and hunting for survival.

Detailed explanation-3: -Solution: Human beings began to cultivate their own food and herding animals. People started to stay at one place for a longer period of time to protect the plants and provide them water. As the people started to depend primarily on agriculture the amount of grains collected from the harvest increased.

Detailed explanation-4: -The agricultural revolution had a variety of consequences for humans. It has been linked to everything from societal inequality-a result of humans’ increased dependence on the land and fears of scarcity-to a decline in nutrition and a rise in infectious diseases contracted from domesticated animals.

Detailed explanation-5: -Agriculture allowed people to stay in one place, and increased food production caused the population density to expand far beyond levels that could be sustained by hunting and gathering alone. This growth in population density provided a critical mass of people to sustain and spread contagious infectious diseases.
