Students from Philippines Science High School, Dipolog City, Philippines, and from Alternative Education Center, Odessa, TX, U.S.A., joined the world's celebration of Zero Discrimination Day on March 1, 2021. Philippine students, through the mentorship of Social Science Teacher Araibo Elumba, created memes depicting Holocaust and World War II. American students described the memes, integrating what they had learned from their History classes. The activity allowed students to exchange visual and verbal descriptions of the biggest discrimination incident in human history, relate it to all forms of discrimination we face today (income, sex, age, health status, occupation, disability, sexual orientation, drug use, gender identity, race, class, ethnicity, and religion), and raise awareness of how they could help promote the global sustainable development goal of reduced inequalities.
