The possibilities for future energy production include fossil fuels, biofuels, solar, wind, hydro-energy, geothermal, and nuclear. Each of these sources has relative advantages and disadvantages. The problem is to produce enough sustainable energy while avoiding unacceptable environmental consequences, especially climate change. Informed choices will help prevent waste, avoid unnecessary disruptions in our lives, and avoid undesirable ecological effects.

Economics is a subject that explores certain social processes in our society, but it is also an investigation into how social processes affect our well-being. For example, economic discussion involves questions about how changes in tax policy might influence economic growth or how price differentials might affect consumer welfare. Economists today regard the Scottish political economist and philosopher Adam Smith as the father of economics.

Evidence shows that experiences in childhood are extremely important for a child’s healthy development and lifelong learning. How a child develops during this time affects future cognitive, social, emotional, language, and physical development, which in turn influences school readiness and later success in life. During early childhood, the human brain grows to 90 percent of its adult size by age three.

Digital technologies, old and new, are not objects that can be packed inside a box. They are a seamless, indivisible combination of people, organizations, policies, economies, histories, cultures, knowledge, and material things continuously shaped and reshaped. Every one of us innovates-in-use our everyday technologies, we just do not always know it. Not only are we shaped by the networked information tools in our midst, but we shape them and thereby shape others.

At the end of the last ice age, the earth’s average temperature increased and glaciers moved rapidly northward. Additionally, rainfall progressively decreased in Southwest Asia and Africa. Under the changed circumstances, humans were unable to sustain themselves throughout the year by hunting and foraging. The human groups, living on different continents, were forced to produce their own food, and farming began within a short span of time all around the globe.
