Answer:
Segregation
Step-by-step explanation:
Segregation refers to the way of seperating or setting things apart from others.
In an environment where there is segregation they are often restricted from going to their neighbourhood especially if the community has limited resources, this will greatly affect the people because they have been set apart or restricted from visiting the place that has much availability of resources .
Segregation can lead to separation of people into different racial or o ethnic groups .
According to the scenario, a food desert is a possible marker of SEGREGATION.
