Seed of an Idea

Description
Yesterday, the tribe came across a vast tract of wild grain, the stalks swaying in the breeze like the wind playing over golden waters. The ground-down grain could feed the tribe twice over, but one of the tribal elders had another idea. Instead of pounding the seeds into flour, she suggests planting half of them so the grasses may return next summer. It is a curious idea, at odds with the nomadic life, but perhaps a harbinger of the future. What should you do?
