Today in human geo we learned about ethnic groups, and language, and religion. There are so many ethnic groups that don't like each other but live in the same country. Also with religion some of the other religions don't like each other. 3 of the top 5 religions are Hinduism, Judaism, Christianity. These are all popular religions but Judaism is practiced way less then like Christianity or Hinduism. Language is a big thing an English is one of the most used languages. English is so well used and known because all the big companies like apple and Nike were created by people who spoke English so most people speak English who work at these stores.
