What factors led to hardship for the Jamestown settlers?

The Jamestown settlers faced significant hardships due to a combination of factors, including harsh environmental conditions, inadequate supplies, and a lack of agricultural knowledge. The settlement was established in a marshy area, leading to disease outbreaks, particularly malaria. Additionally, conflicts with Indigenous peoples and the settlers' reliance on trade rather than self-sufficiency exacerbated their struggles, resulting in food shortages and eventual starvation. These challenges contributed to a high mortality rate in the early years of the colony.
