John Rolfe taught the Jamestown settlers how to plant and harvest tobacco which saved the colony's economy.
Explanation:
Many settlers from Britain came to settle in Jamestown in North America. They were funded by Virginia company which is a joint venture company founded in Britain. John Rolfe is the first American settler who cultivated tobacco for the first time in James town and helped the colony to survive the harsh climatic conditions that challenged the settlers.
He was the first to develop the cultivation of tobacco which was sent to the home land and it earned huge profits. He also attained the support from the Powhatan who were the Native American tribes with which he was successful in learning the cultivation of tobacco which ultimately earned profits and stabilized the English colonies in North America.
