Question

How can we explain why all of this diversity exists

Answer 1

Answer:

Ours is a very diverse society—and increasingly so. Already in many parts of the country, non-Hispanic whites comprise less than 50 percent of the population, and by 2020 an estimated one in three Americans will be a person of color, as will be about half of all college students. But “diversity” means much more than a variety of racial and ethnic differences. As we’ll use the term here, diversity refers to the great variety of human characteristics—ways that we are different even as we are all human and share more similarities than differences. These differences are an essential part of what enriches humanity.

Answer 2

The reasons of diversity could be the variations among human in the forms of color, ethnicity, gender, physical bearings, socio-economic rank, generation, physical experiences, spiritual faiths, culture, political beliefs, or other ideologies.
