This document discusses diversity in the world and defines prejudice, stereotypes, discrimination, and the harms they cause. It provides examples of direct and indirect discrimination based on attributes like age, disability, gender, race, and religion. Discrimination can negatively impact people physically, emotionally, socially, and financially by causing anxiety, depression, loss of interest and withdrawal.

The document urges parents to teach children about appreciating differences from a young age to help prevent prejudice and discrimination.
