Final answer:
Community gardens do not contribute to a prescreened food desert; they are actually beneficial. Food deserts are often characterized by limited access to fresh foods and may be more prevalent in low-income areas without readily available transportation.
Step-by-step explanation:
The components that contribute to a prescreened food desert include limited access to fresh produce, lack of transportation to grocery stores, and low-income neighborhoods.
However, the presence of an abundance of community gardens does not contribute to a prescreened food desert.
In fact, community gardens are often part of the solution to food deserts, as they increase the availability of nutritious foods in areas where these are normally scarce.
