Discrimination can take many forms including discrimination by social class, skin color, religion, age, national origin, and species. Social class discrimination is based on one's resources and social standing. Skin color discrimination treats people differently based on their color and can be seen within racial and ethnic groups. Religious discrimination involves treating people unequally due to their religious beliefs and customs. Age discrimination impacts both the young and old. National origin discrimination includes treating people unfairly based on their ethnicity, accent, or perceived background. Discrimination by species is wrong as it implies some groups like animals do not deserve equal consideration just because they are a different species, but all who live on Earth have equal rights.
