In his farewell address, President George Washington gave America several pieces of advice. The two most prominent are:
1) Avoid the creation of political factions (aka political parties)- Washington believed that political parties would only cause individuals to be more divided in American society. He felt that these organizations would cause more problems than they would solve.
2) Avoid foreign entanglement- Washington wanted the United States to stay out of foreign affairs. Washington felt that only problems would result from getting involved in the affairs of other countries.
Answer:
The artifact that most represents the early twenty-first century is the smartphone. This represents how important technology had become and how it was changing features at sites in the lives of people from that time. The ecofact of this era is evidence of global warming that society tried to resolve with measures like carbon offsets.
Explanation:
The anthropologists from the future will probably note that the smartphone is one of the most important artifacts found with human beings in the early twenty-first century. It made technology more portable and the younger generations tend to text each other more than they use the cellphone aspect of the smartphone using applications. This would be a reason for there being features in households increasingly integrated with technology and of their being a relative lack of written documentation as many things are digital. It is hoped that society saved some digital archives for societies to study the time period in the future. In terms of ecofacts, it is clear that climate change exerted a lot of pressure on society in the twenty-first century and as natural remains there were efforts to stop global warming by reducing CO2 emissions. More parks and forests and other environmental projects were protected as a way to offset carbon production by entities like airline companies.
