In her youth I would make my best attempts to instill in any girl I loved (cleanly and purely) values and ethics that would steer here away from the porn industry. We would talk about her goals in life. I would see that she had wholesome activities in her life, e.g., ballet, sports, arts, music. I would encourage her to do well in any academic endeavors, including going on to earn an advanced degree, or to seek a profession that would prove beneficial to herself and to society, e.g., a medical career.

Love. Guidance. Support. Being there for her. These things lead to more positive life choices.
