What economic activity helped save the Jamestown settlement?

The economic activity that helped save the Jamestown settlement was agriculture. The settlers began growing grain crops, such as corn and wheat, with the help of Native American agricultural techniques. Trade with local Native American tribes also became important in obtaining provisions, providing goods, and exchanging knowledge. This economic activity, combined with other measures such as disease control and military protection, provided just enough to keep the settlement afloat and established Jamestown as the first successful British colony in North America.
