Explain the widespread use of slavery- Microeconomics

(a) Two of the most important developments that greatly increased the survival success of early humanoids, was
1. the ability to make and use primitive tools for hunting, and

2. the ability to find and process gold into trade items, and

3. the domestication of fire about 300,000 years ago.

4. the domestication of dogs as hunting partners about 200,000 years ago.

5. the division of labor where men became the gatherers and women the hunters.

6. the migration out of Africa.

7. the planting and harvesting of crops beginning 100,000 years ago.

(b) One of the most dramatic changes in early human history is called the Neolithic revolution which began about 12,000 years ago in the Fertile Crescent. The two key developments of the Neolithic revolution were

1. the domestication of certain animals such as goats and cattle

2. the migration out of Africa

3. the selective breeding and cultivation of crops such as wheat and barley

4. The development of early forms of writing

5. the development of gold based money

6. the development of water wheels

7. the domestication of the horse

(c) The Middle Ages has often been characterized as the “Dark Ages”, but with respect to the human use of energy, several key developments were

1. the development of bigger and more effective water wheels.

2. the use of coal to make coke for use in iron and steel manufacturing.

3. the beginning of the development of effective wind mills.

4. the use of wood to make charcoal for cooking, making ceramics, and the smelting of metals.

5. the effective harnessing and use of horses.

6. the discovery of electricity.

7. the widespread use of slavery.

(d) The industrialization period of the late 1800’s saw several new forms of energy developed, including

1. more effective use of humans and animals to power machinery using treadmills.

2. the use of coal to generate electricity.

3. petroleum for lighting, lubrication, fuel oil and many other products.

4. the use of coal to make “town gas”.

5. the first use of solar to generate electricity directly.

6. the widespread use of coal for a large variety of heating, transportation, industrial, and residential purposes.

7. the energy of waves and tides to power industrial machinery
