In places like West Asia, Egypt, India and China climatic changes led to the emergence of farming as the dominant form of living. These people also domesticated animals. However, agriculture was the dominant survival strategy for them. When food production and animal domestication combined as a mode of life it was a revolution. The transition from foraging to farming is one of the turning points in our history. The seasonally mobile life of hunter-gatherers, who obtained their food from wild plants and animals, was replaced by the settled life of farmers, who cultivated crops and raised domesticated livestock. This shift to sedentary life led to the growth of population and village settlement, the development of crafts such as pottery and metallurgy, and eventually to states and cities.
Food production and animal domestication represented a changed outlook for food quest. It represented a planning not for a day but for a season – for the long term. This new agricultural economy expanded at the expense of the old foraging way of life. Slowly and steadily agriculture became the dominant mode of life. Even today it remains the dominant occupation of the majority of humans. Last two hundred years of industrial revolution have reshaped the contours of the world. However, even now in a country like India almost 75% of the people are agriculturists. The soil they work on is an artificial soil fashioned by thousands of years of labour.
