This document discusses diversity in the world and defines prejudice, stereotyping, 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. It also lowers productivity in businesses and societies by creating disgruntled and distrustful employees. Strong laws exist to protect against discrimination, and prevention requires open-minded parenting, education of children about appreciating differences, and fostering respect for all people.
