Why do the people of Ember eat these foods?

The people of Ember eat the foods available to them primarily due to the scarcity of resources in their underground city. Their diet consists of whatever can be grown or preserved, including canned goods and root vegetables, as they have limited access to fresh produce and protein sources. This reliance on specific foods reflects their adaptation to a closed environment where sustainability and survival are paramount. Additionally, the foods they consume are tied to their cultural practices and the need to maintain a sense of community in challenging conditions.
