Environmental Factors Leading to Civilization Along the Nile

A.) The two most significant environmental or physical geographic factors that contributed to the development and expansion of the United states had to be the Gold Rush, and the Irish Potato Famine. The Irish potato famine was devistating to Ireland and laid waste to it's population, but ended up spurring Irish immigration to the United States, leading to both growth and expansion. The gold rush that took hold in the United States was one of the biggest factors that pushed people west and lead to a greater settlement of the west coast and all areas between. These two major events helped to shape the country that we know today. The Irish Potato Famine was one of the most significant environmental factors that helped develope and expand the United States because it not only lead to a population swell, but contrubuted to our work force due to the large number of immigrants that came to the U.S. as a result of it. Before the famine, the Catholic Irish peasents lived a very poor lifestyle and were constantly under fear of being evicted by their land lords as their farms were downsized and their rents were raised. They grew potato crops in the fertile Irish soil and used those crops to pay their rents and feed their families. This was many families' sole source of income and nutrition. When the potato famine began in September of 1845, the potato crops failed universaly in Ireland, something that had never happened before. The poor Irish had been acustomed to a bad crop in a spot or two and they always had adjusted to circumstances before, and there was little loss of life over this previously. From 1845 and for the next 4 years, the crops would fail repeatedly and this caused wide-spread death, from both starvation and opportunistic infections such as typhus, that mowed people down by the thousands in their hunger weakend condition. There were many theories about just why the crops failed, both superstitious and religious, but we know now that it was the fault of a
