Should I adopt a black child if I live in a non-diverse region?

I live in a part of the country that is about 90% white and 10% Hispanic. There are very few black or Asian people. From what I understand about transracial adoption, it's very important that an adopted child have "community mirrors," that they have the opportunity to encounter mentors, friends, neighbors, and professionals of their same race so they can develop a healthy racial identity. Does that mean I shouldn't consider adopting a black child? Would that be unfair for them? Is there a way to help a child cultivate a healthy race identity within a community that doesn't have a lot of diversity?
