What are 3 reasons that Jamestown settlers died so quickly?

Jamestown settlers faced a harsh environment, leading to food shortages and malnutrition due to the lack of farming skills and poor planning. Additionally, disease from contaminated water and the presence of mosquitoes contributed to high mortality rates. Conflicts with Indigenous peoples further exacerbated their struggles, limiting their access to resources and support. Together, these factors created a dire situation that resulted in the rapid decline of the settlement's population.
