Question 5

Explain why quality of life is critically dependent upon energy use and consumption.

Revolt · Accepted Answer

Research has shown that there is a direct relationship between the amount of energy used and overall economic activity in a country. In many ways quality of life is also directly related to the level of economic activity in a country because sufficient economic resources can ensure the physical components required for a high quality of life. In this way, energy use directly impacts quality of life by impacting economic activity.

While there are many elements that might be considered important for a quality life, the ultimate determination of what defines a quality life is a personal judgement based on individual experiences and values. People in different socioeconomic situations will value different things; a homeless person will likely value shelter and food higher than convenience and luxury. Different experiences and relationships will result in different priorities.

Revolt · Accepted Answer

Hunter-gatherer societies did not farm or raise livestock; they collected the resources they required from the local environment. In order to ensure a continuous supply of needed resources, hunter-gatherer societies followed their food sources and moved frequently.
