ANswer is Nationalism
World-systems theory (also known as world-systems analysis or the world-systems perspective),[1] is a multidisciplinary, macro-scale approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis.[1][2]
"World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and the periphery countries.[2]Core countries focus on higher skill, capital-intensive production, and the rest of the world focuses on low-skill, labor-intensive production and extraction of raw materials.[3] This constantly reinforces the dominance of the core countries.[3] Nonetheless, the system has dynamic characteristics, in part as a result of revolutions in transport technology, and individual states can gain or lose their core (semi-periphery, periphery) status over time.[3] This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy.[4] For a time, certain countries become the world hegemon; during the last few centuries, as the world-system has extended geographically and intensified economically, this status has passed from the Netherlands, to the United Kingdom and (most recently) to the United States.<span>[3]</span>
Answer:
By a mix of human and physical geographic evidence.
Explanation:
Civilizations can end due to natural causes. Volcanic eruptions can be devastating for people living close to it. Checking rock age and strata with any historical references could explain. Data from ice core could indicate changes in the atmosphere. A change, such as increased drought, in regions, might end up causing food shortages and the end of civilizations.
Human evidence can provide the answers too. Migration patterns may explain this, such as the Europeans arrived in the Americas. The land has a carrying capacity. Studying the population might indicate the carrying capacity was exceeded, such as Easter Island.
Answer:
Yes, with a condition.
Explanation:
Renewable energy sources and have always been available on the planet, but until recently, humans have not had the technology necessary to harness them. Since solar and wind energy are limitless, it clearly makes sense to invest the necessary amounts of money to build one-time infrastructure capable of powering all human activity without depleting natural resources.
The condition that is a prerequisite already being fulfilled is that technology be developed to make alternative energy solutions <em>economically viable and profitable </em>enough to be able to compete with traditional non-renewable sources.
