We are not alone

-Well, it seems like other people are taking care of that, and although I really want to help, I also need to figure this out before dark- Aurora said to herself
Walking on the beach and picking up all plastics she could encounter, a mysterious voice yelled at her from the distance:
-HEY YOU! THE LITTLE GIRL!, COME OVER HERE!-
Aurora, as a smart kid, never followed strangers anywhere, so she ignored the voice. She also noticed however that the mysterous voice came from a family man, and that all of his family were wearing the same T-shirts with the same logo.
-What is Ocean Legacy?- asked Aurora, from a safe distance just to be sure
-It's the organization that recuits volunteers, like us, to help clean the beaches from plastics. I saw you wandering around picking up bottles so I assumed you were one of us. Do you want to join?- asked the man
-Let me think... Should I sign up, or go back and help that voice from earlier?-
