For the hunter-gatherers who cooked food over the campfire, the energy was used with an efficiency of less than 5% (the energy that benefited the user, such as cooking the food, warming the air, providing light, etc.). When humans began using hearths as they became more sedentary, their energy efficiency increased. As humans built dwellings and fireplaces, energy efficiency increased, and today, energy efficiency in advanced industrialized civilization reaches more than 35%. As humans kept increasing their gross energy input and the efficiency in using the energy, the . Just as , an increased energy surplus meant an easier life and a better chance of survival. In recent years, while the USA’s GDP-per-capita has risen, its energy-consumption-per-capita . Some have argued that it shows how much more efficient the USA’s economy has become, but it is more likely related to the USA’s de-industrialization, as heavy industry has moved to low-wage nations with weak environmental laws. The USA imports more finished goods in which the energy for mining and manufacturing them was used in other nations, like the imperial subsidy that the British received from their colonies, but far more pronounced when the USA is receiving finished industrial goods and not raw materials, as the British received from India.

Prosimians have simple social organization; most nocturnal prosimians lead solitary existences. have societies of up to 20.
