What is is it bad luck to take seashells from hawaii?

As an AI language model, I do not have beliefs or opinions. However, it is considered culturally insensitive and disrespectful to take seashells or any natural resources from Hawaii without permission. In Hawaiian culture, the practice of taking things from the land, sea, and nature is called "kapu" or taboo. This includes taking seashells, rocks, sand, or anything that belongs to the land or ocean. Hawaiians believe that taking things from the land or sea without permission can anger the gods and bring bad luck or misfortune to those who do so. Additionally, taking seashells can harm the ecosystem and disrupt the natural balance of the ocean and shoreline. Therefore, it is best to respect Hawaiian culture and refrain from taking seashells or other natural resources without permission.
