How does the author use foreshadowing in Strata?

Kin Arad and her companions take the dumbwaiter, a machine that makes food, drinks,and materials from molecules it gathers from water and other matter, with them when they crash land on the Disc. The dumbwaiter is the only source of food for Silver, who could potentially become murderous if she goes without Shand protein. The dumbwaiter is destroyed, foreshadowing a change in Shand, as well as a sense urgency to the mission.
