Answer:
Slavery
Explanation:The United States became a continental nation with the purchase of Louisiana from France in 1803 and the settlement of the lands beyond the Appalachian Mountains. Westward expansion fueled conflict with Native populations and led to their forced removal. By 1820, 2 million Americans lived west of the Appalachians, out of a total national population of 10 million. The regional cultures that had developed along the Atlantic Coast—New England, Middle Atlantic, Chesapeake, and Carolinas—were transplanted into the Old Northwest (Ohio, Indiana, Illinois, Michigan, and Wisconsin) and the Old Southwest (Arkansas, Kentucky, Louisiana, Missouri, Tennessee, and Texas). But although Americans had begun to identify themselves as a nation, they were divided by sectional interests that deepened with rapid industrialization and the question of slavery.
Answer:
There would be no power to use your fridge or freezer, telephone lines would be down and phone signal lost. Your mobile phones will be useless as the battery dwindles, with no back up charging option. Your gas central heating won’t work and your water supply would soon stop pumping clean water.
It sometimes takes a lot for some people to realise that without electricity it isn’t just internet and Wi-Fi that is affected, it also means no cash machines, no lifts, no power to keep the factories going, and no petrol pumps. It is seen as the end of normality as we know it.
Two critical things we need in our life are heating and water, and without electricity, these are both compromised. The gas central heating in our homes works with electric controls and circulating systems and pumps. Water systems are dependent on electrically managed systems and pumps, so even if water is still accessible in your home, you would still have to purify it before drinking.
