Cultural sustainability is about making sure that a culture can be kept alive and safe for future generations. It means not just looking after the things that we can see, like buildings and artifacts, but also the things like stories and traditions that can't be seen. It is important to make sure that a culture is passed down from one generation to the next, so that it does not get forgotten or lost forever. To do this, people can work together to share their stories, teach the younger generations, and do things like create museums and cultural centers to help keep a culture alive.
