World Populations and Development1.)     The Neolithic and Industrial RevolutionsThe two changes in the using up of the earths resources that had the greatest effecton the world existence were the neolithic and the industrial revolutions.The neolithic revolution (a.k.a. agricultural revolution) was a change in the way of life of our ancestors. It took place about 8000 years ago among varioustribes in Asia and the Middle East. It included a transition from foraging andhunting to the jejuneness of animals (most probably starting with the dog)and to farming. Tribes sett conduct in fertile areas and formed agriculturalcommunities umteen of which grew into villages and cities. This relatively stableway of life and the more authentic food supply (and surplus) led to thedevelopment of new professions, to labor specialization and ultimately to thestratification of these societies. Improved conditions of life led to somewhat seven-day life spans. Nevertheless popul ation growth remained low due to lavishlyinfant mortality rates. The impact of the neolithic revolution was not as muchon immediate population growth (even though it did use up a long term impact onpopulation growth) as on the material and spiritual development of the humanrace. It is widely regarded as the beginning of civilization. Industrialrevolution was another process of change. It was the process of changemuscle power with machine power. It took place in the 18th vitamin C in Europeand is still happening in many separate of the world. In many characteristics ithas been similar to the neolithic revolution it increased production, it led tothe use of resources that had been mostly unused until then and it improved theoverall choice of life. It also led to changes in the structure of society.What was different, was its impact on population growth. It was quick and easilynoticeable. Advanced sanitation, hygiene and medicine led to lifelong life spansand declining death rate s, with the birth rates remaining high. This resultedin a high rate of population growth that still continues in many countries. Theinformation revolution is the process of change that began in the second one-half ofthe 20th century in the developed countries of the world. It is the process ofsubstituting " brain power" with "machine power". It leads to increasedproduction and has the potential to stool a more even distribution of theworlds population on the prove of the earth. It also has the potential todecrease the differences between the less developed and the passing developednations of the world. Then again it also has the potential to increase thosedifferences. It causes changes in the structure of society.
