Some European countries, including England, were in competition to increase their wealth and power by expanding their empires to America. The first permanent English settlement in America was Jamestown, founded in 1607.
The Jamestown settlers faced a number of hardships, three of the most prominent hardships were food shortages, disease, and hostile Indians. The colony was originally founded as a money-making enterprise, so the early settlers did not place enough emphasis on growing food.
