Step-by-step explanation:
Teenagers may not treasure their cultural heritage because of the fact that people don't recognize it. Lots of teenagers want to educate people on their culture, but the reason that some teenagers don't treasure their heritage is because people don't listen to them. I feel, personally, that if more people were educated on the more diverse cultures, teenagers would be more open about their culture and heritage.
Another reason that teenagers wouldn't treasure their heritage is because of the reactions they would get. In every place you go to, there is always going to be someone who puts you down for something out of your control, like culture. People may start making fun of you for your culture, and may also start stereotyping you. This may cause teenagers to feel insecure about their culture, causing them to be more secluded about it.
