A young boy is visiting his grandfather at his beach house. He's intrigued by a collection of seashells on a coffee table. He's never seen shells except for in books and at the museum. He asks his grandfather about them. The old man remembers collecting the shells with the boy's mother when she was his age. The grandfather explains that there are no more shells because of ocean acidification. The boy asks why people didn't stop polluting. They didn't see the beauty in a simple shell, he answers.
