Race and ethnicity

Race and ethnicity are ways of classifying humans based on ancestry. Race is a broader term, while ethnicity is generally a subcategory of race. Different races and ethnicities have differing physical characteristics, as well as different languages, religions, and cultures. There are also some ethnicities who have origins from multiple races, such as the Cape Coloureds of South Africa.

Humans are often classified into five different races: Europeans, Africans, Asians, Native Americans, and Australian Aborigines.

Racism
Tragically, there has been a large amount of racism in history. The effects of it still exist today. In the United States, African Americans are on average significantly poorer than European Americans. Black people were originally slaves. Black people didn't have the legal right to vote until 1870, when the 15th Amendment was passed. Even then, people still prevented them from voting, through social pressure, literacy tests, and poll taxes. It was similar to how abortion is technically legal, but still forbidden, in many parts of the United States today. The different peoples of the world need to tolerate one another.
